Utility / service bodies
The classic work truck: lockable compartments down both sides for tools and parts, open bed or enclosed top. Electricians, HVAC techs, plumbers, and general contractors live out of these.
01 · The quick comparison
Same chassis family, completely different jobs
Both are work trucks on medium-duty chassis, and that is about where the similarity ends. A service truck sells your labor on site. A tow truck sells moves and recoveries. The table below is the whole decision in one glance.
| Service trucks | Tow trucks | |
|---|---|---|
| The job | Bring the shop to the job site — repairs, installs, field maintenance | Move dead, wrecked, or illegally parked vehicles — recovery and transport |
| Body types | Utility / service bodies, crane bodies, mechanics (lube) trucks | Wreckers (wheel-lift), rollbacks (carriers), rotators |
| Key equipment | Locking tool compartments, service crane, air compressor, welder, lube skids | Winch, wheel-lift or sliding flatbed, outriggers, warning light bar |
| Who buys them | Contractors, fleets, independent mechanics, municipalities, farms | Tow companies, auto auctions, roadside assistance, impound lots |
| What moves the price | Crane size and certification status, body condition, chassis miles and hours | Bed and winch condition, wrecker unit age, chassis miles and hours |
| License note | Heavier setups can require a CDL — check the truck's GVWR against your state's rules | Heavier setups can require a CDL — check the truck's GVWR against your state's rules |
| Used watch-outs | Crane inspection papers, PTO and hydraulics, compartment rust | Winch cable condition, bed hydraulics, frame cracks and old welds |
Our read: don't buy the truck and then go looking for the work. Line up the work first — contracts, accounts, or a route — then buy the truck that fits it.
02 · Service trucks
A rolling workshop that bills by the hour
A service truck exists so a skilled tradesperson never has to drive back to the shop. If your money comes from labor performed on site — turning wrenches, pulling wire, swapping parts — this is your category.
Crane bodies
A service body with a hydraulic crane mounted behind the cab or at the rear. Lifts motors, transformers, pipe — anything your back shouldn't. If the crane doesn't have current inspection papers, price the truck like it doesn't have a crane.
Mechanics / lube trucks
Built for field maintenance: air compressor, welder, lube skids, fluid tanks. Mines, quarries, farms, and big fleets run these so the equipment never has to come to the shop.
Who buys them
Contractors buying their first real work truck, fleets standardizing field service, independent mechanics going mobile, and municipalities keeping their own equipment running. The common thread: the truck supports skilled labor, it doesn't replace it.
Buying used? Run the PTO and cycle every hydraulic function — crane, outriggers, compressor — before money moves. Open every compartment and look for rust at the seams and floors. Ask for service records and the crane's inspection papers. A cheap truck with a dead crane is just an expensive pickup.
Financing a service truck? Get pre-approved before you shop — it makes you a cash buyer at the negotiating table.
Get pre-approved03 · Tow trucks
The truck IS the business
A tow truck doesn't support your work — it is the work. Every tow, recovery, and transport is a ticket. That makes the truck's uptime your revenue, which changes how you should buy.
Wreckers
The classic tow truck with a wheel-lift or boom. Light and medium wreckers handle daily tows, repos, and roadside calls. Fast to hook, fast to go — built for volume.
Rollbacks (carriers)
A flatbed that slides back and tilts so the vehicle drives or winches on. The go-to for hauling cars, low-clearance vehicles, and equipment without dragging anything.
Rotators
The heavy end of the industry: a rotating boom for the biggest recoveries — overturned semis, heavy equipment. Serious iron, serious money, and serious operating cost to match.
Who buys them
Tow companies expanding a fleet, new operators starting with one truck, auto auctions moving inventory, and roadside assistance contractors. The buyers who do well have the work lined up — police rotation, motor clubs, or dealer and auction accounts — before the truck arrives.
Buying used? Spool the winch all the way out and read the cable — fraying, kinks, or bird-caging means replacement before the truck earns a dime. Run the bed or wheel-lift through its full cycle and watch for slow or jerky hydraulics. Check the frame for cracks and old welds, especially behind the cab. Outriggers should deploy smooth and hold firm.

Get pre-approved04 · Which fits you
Match the truck to the paycheck
Buy the service truck if you…
- sell skilled labor performed on site — the truck carries your shop to the job;
- have contracts, a trade, or fleet accounts that keep the calendar full;
- want the truck to support work you already know how to do;
- can keep a crane inspected, certified, and maintained without drama.
Buy the tow truck if you…
- want to sell tows and recoveries directly — the truck is the revenue;
- have accounts lined up: police rotation, motor clubs, auctions, or dealers;
- can run dispatch and handle the hours this business actually demands;
- understand that downtime isn't an inconvenience here — it's lost income.
Straight talk: a service truck without contracted work is an expensive toolbox, and a tow truck without accounts is an expensive ornament. The truck follows the business plan — never the other way around.
05 · Used-buying checklist
Check these before money moves
Used work trucks are where the deals — and the disasters — live. Work through this list on every truck, service or tow. It takes an hour. Skipping it can cost you thousands.
Frame and body
Look for cracks, rust-through, and sketchy welds — especially behind the cab and at body mounts. A bent or patched frame is a walk-away.
Hydraulics and PTO
Engage the PTO and run every powered function: crane, bed, winch, outriggers. Slow, jerky, or leaking hydraulics means money out of your pocket.
Crane papers
A service crane should come with current inspection records. No papers, no premium — price the truck as if the crane is decoration.
Winch and cable
Spool the cable out fully. Frayed, kinked, or bird-caged cable needs replacing before the truck does real work.
Outriggers
Deploy them fully. They should move smooth and hold firm — they're what keeps the truck upright under load.
Service records
Oil, filters, and repair history tell you how the last owner treated it. Gaps in the records aren't a dealbreaker, but they are a negotiating tool.
Rule of thumb: test every powered function before money moves. A truck that "just needs a little hydraulic work" needs your wallet.
06 · Parts, pricing & local shops
Keep it running without getting robbed on parts
The purchase price is only the entry fee. Parts and shop labor decide whether the truck makes you money or eats it. Here is where owners actually buy parts, how to keep pricing honest, and how to find a diesel shop near you.
Where parts come from
- OEM dealer parts counters — the exact part, the highest price. Worth it for electronics, injectors, and anything warranty-sensitive.
- Heavy-duty aftermarket distributors — national suppliers that stock the same categories (brakes, filters, suspension, lighting) for less than the dealer. Get quotes from more than one.
- Local independent parts houses — the counter guys who know your truck by sight. Often the fastest option when you're down and need it today.
- Salvage yards — cabs, doors, tanks, and body parts at scrap-plus pricing. Never buy safety or wear parts used.
Where trucks come from
- Commercial truck centers — dealers that sell and service work trucks. Higher prices, but inspected inventory and financing on site.
- Independent lots — smaller dealers, mixed quality. The checklist above matters double here.
- Auctions — fleet trade-ins at wholesale-ish prices, sold as-is. Bring your inspection list and a hard ceiling.
- Private sellers — often the best-maintained trucks, no dealer markup. Verify the title and service history yourself.
Getting good pricing: get three quotes on any big part or job. Ask parts counters about shop or fleet pricing — many have it and won't offer it. Watch core charges on alternators, starters, and turbos, and compare OEM vs. aftermarket on wear parts where the brand doesn't matter. On trucks, walking in pre-approved turns you into a cash buyer, and that's where the real discount lives.

Tap the button and we'll pull up heavy-duty truck repair shops around your current location. Your location stays in your browser — it only goes to Google Maps when you tap.
What to look for in a shop: they work on medium- and heavy-duty trucks (not just pickups), they have the diagnostic software for your engine, they warranty their labor in writing, and they'll show you the old parts. A good shop answers "what's it going to cost" before they touch the truck.
07 · Financing
Get pre-approved before you shop
Almost nobody pays cash for a work truck — and sellers can smell a buyer who is still figuring out the money. Getting pre-approved first tells you your real budget and turns you into a cash buyer at the negotiating table.
Know your number before you fall in love with a truck.
Pre-approval takes a few minutes and costs you nothing to check.
How commercial truck financing works
- It is its own world — separate from consumer auto loans, with lenders who specialize in work trucks and equipment.
- Lenders look at your credit, your business history, and the truck itself as collateral.
- Expect the down payment conversation to be bigger than buying a pickup — commercial lenders usually want more skin in the game.
- Older, high-mile trucks can be harder to finance — the truck's age and condition matter to the lender too.

09 · FAQ
Questions worth asking first
Sometimes. Heavier trucks can trigger CDL requirements depending on the truck's GVWR and your state's rules — and tow trucks doing interstate work have their own wrinkles. Check the specific truck's ratings against your state's CDL requirements before you buy, not after.
New buys you a warranty and known history at the highest price. Used saves serious money but you're buying someone else's wear — which is exactly what the checklist above is for. Most first-time buyers do best with a well-inspected used truck and money left over for the surprises.
Age, mileage and engine hours, and — biggest of all — the condition of the mounted equipment. A clean chassis with a worn-out crane or tired winch isn't the deal it looks like. Certification status on cranes and the service history move the number more than the cab's cosmetics.
It's a separate lending world. Commercial lenders evaluate your credit, your business history, and the truck itself as collateral — and they typically expect a larger down payment than consumer auto. Terms, rates, and requirements vary by lender, so compare more than one offer.
Yes — many commercial lenders finance used trucks. That said, older or very high-mile trucks can face age limits, shorter terms, or bigger down payments depending on the lender. The truck's condition matters to them, not just to you.
The papers first: a working crane should have current inspection records. Then run it — full rotation, full extension, outriggers down — and watch for leaks, cracks, jerky movement, or anything that doesn't feel right. A crane that can't prove it's certified gets priced like scrap leverage, not like equipment.
