About RHD Heavy Duty Diesel truck & engine repair

RHD Heavy Duty Diesel in Coolidge works on over-the-road trucks, dump trucks, cement trucks, buses and RVs. Diesel pushers and motorhomes are part of the lineup, so a breakdown on your trip is not out of place here. The shop handles engine rebuilds, inframe and out-of-frame, plus diagnostics, suspension, oil service and trailer repair. Mobile roadside work and welding are on the list too. Reviewers keep coming back to the mechanic, often by name. One driver whose rig nearly caught fire from a differential says the fix came fast. Another says no other mechanic could figure out the problem and this one did in about 20 minutes. A motorhome owner had an alternator replaced and was back on the road. Others mention fair prices and call the mechanic honest, though one notes the shop is busy and diagnostics took a few days. Weekend calls happen, at least by one account of a Sunday trailer repair. Hours are posted, and it is not a 24/7 operation.
