Big Wheel Diesel & Wrecker Service is a diesel repair shop and 24/7 wrecker towing business based at 42241 S Morrison Blvd in Hammond, LA. Diesel repair is its main trade, with towing alongside it. It comes to you for breakdowns, offering "mobile repair services, handling breakdowns on-site," and you can also bring your RV to its shop.

It names "truck, trailer, RV, and bus repair" along with roadside assistance and light to heavy-duty towing. Its systems include air brakes, air suspension, axle alignments, transmission and differential repair, trailer repair, tire service and air conditioning service. Its brands include Cummins, Detroit Diesel, Caterpillar, Allison Transmissions and Onan. It lists no RV-only systems such as slide-outs or refrigerators, so ask whether it can handle yours. It serves "Hammond & surrounding areas," and names Ponchatoula too.

It does not publish a trip fee, hourly rate or diagnostic fee, so ask about the trip fee when you call. It lists its hours as 24 hours a day, seven days a week. Its stated response time is "In many cases, tow trucks can arrive within 30 to 60 minutes." Ask about a warranty and about licensing and insurance, since it states neither.

Its certifications are Authorized Onan Dealer, Authorized Cummins Dealer, Authorized Spartan RV Chassis Center, Authorized NAPA Service Center and Certified PDI Dealer. Onan makes generators that many motorhomes carry, and a Spartan RV chassis sits under some motorhomes, so those names matter if your rig has either. An authorized dealer works with the manufacturer's parts and training. Josh Burch, P.E., is President / General Manager, and the shop calls itself a "family-owned shop serving Hammond since 1982." Google rates it 4 stars from 193 reviews.

This is a good fit for an RV owner around Hammond or Ponchatoula who needs roadside help at any hour, or who has an Onan generator or Spartan RV chassis to get looked at. Owners with a slide-out, refrigerator or other RV-only system should ask first whether it does that work.
