12V & Charging Electrical
House and starting batteries, alternators and isolators, wiring, lighting, and 12-volt panels — diagnosed back to the cause, not just the symptom.

One shop for the kitchen and the chassis. We handle 12-volt and generator electrical, LP/propane lines, appliance repair and replacement, custom fabrication and upfits, and the engine, chassis and diesel work underneath — so your mobile kitchen spends less time parked and more time earning.
Run a food truck long enough and you learn the hard part isn't any one repair — it's the juggling. The auto shop fixes the engine but won't touch the propane. The kitchen guy wires the equipment but can't inspect the brakes. So a problem that should be one appointment turns into two vendors, two waits, and a truck sitting idle in between.
NextGen AutoWorks works the kitchen and the chassis. We're a full-service auto and diesel repair shop in Grantville, PA, just off I-81 Exit 80 — close to Hershey, Harrisburg, and Lebanon — and the same shop that services your truck's engine, transmission, brakes, and tires also handles the 12-volt and generator electrical, the LP/propane lines, the cooking appliances, and the fabrication and upfitting that make it a working kitchen. One shop, one point of contact, one timeline.
We treat downtime as part of the job. A truck that isn't rolling isn't earning, so we diagnose quickly, give you an honest timeline before any work starts, and stage repairs and builds to get you back to your events as soon as it's safe to do so. We can't promise same-day on every job — parts and fabrication take what they take — but you'll always know where things stand. Qualifying repairs may be backed by the NAPA Peace of Mind Warranty — 24 months / 24,000 miles, honored nationwide when current NAPA terms apply.
Repair, service, and build-out across the systems that keep a mobile kitchen working — and the vehicle it all rides on.
House and starting batteries, alternators and isolators, wiring, lighting, and 12-volt panels — diagnosed back to the cause, not just the symptom.
Onboard generator service, inverter and converter repair, transfer switches, and 30-amp / 50-amp shore-power connections so your equipment runs wherever you park.
Propane gas lines, fittings, regulators, and appliance connections, with system leak checks. We confirm the scope of LP work with you up front — permit rules vary by build and jurisdiction.
Griddles, fryers, ranges, refrigerators, freezers, and water heaters — repaired or replaced and tied back into the truck's power and propane correctly.
From a single bracket to serving windows, shelving, counters, equipment platforms, and structural reinforcement — fabricated and installed, then wired and plumbed to work.
Engine, transmission, brakes, suspension, tires, and A/C on gas and diesel chassis — including the medium-duty platforms many trucks are built on — by diesel-experienced technicians.
…and more: PA state inspection (by vehicle class), brakes, tires, A/C, and preventive maintenance to keep you road-ready all season. We don't certify hood fire-suppression systems or handle health-department compliance — we'll point you to the right specialist for those.
From cheesesteaks to cookie dough — mobile kitchens we've kept rolling around Hershey, Harrisburg, and Central PA.



A few of the local mobile kitchens we've kept rolling. If you've eaten at an event around Hershey or Harrisburg, there's a good chance one of these trucks was on our lift first.

"I have a small motorhome and have a leaking valve, I went to 8 tire companies around Harrisburg and no one want to help me. I went to Camping World and Carl refer me to Brandon's because they always work with them. I met Dan and he took me right away and fix all my tire problems. I really recommend those peoples to anyone specially RV travelers. I rarely find a service like that. Thank you guys."
"Helpful and knowledgeable. Unfortunately they couldn't inspect my medium duty truck, however they sent me in the right direction."
"We just had our vehicle inspected by Garth!!! What a great, professional mechanic and business. Thanks Garth and Brandon’s Tire and Service !!! Ferguson Family"
Yes. Food trucks and concession trailers are a real part of what we do at NextGen AutoWorks in Grantville. We work the vehicle and the build — engine, transmission, brakes, suspension and tires on the chassis (gas or diesel), plus the systems that make it a mobile kitchen: 12-volt and charging electrical, the onboard generator, inverter and shore power, LP/propane lines, and cooking appliances. Local operators like Philly Cheesesteak Co. On The Roll, Café Haj Paj, East Coast Mini Donuts, and Yianni's Gyros are among the food trucks we've serviced. Call (717) 473-5997 and we'll confirm what we can take on for your rig.
