Call Trent: 920-484-8625Built by two guys who have spent years working on trucks, equipment, engines and just about anything mechanical.
Arnold’s Diesel Repair LLC started in January 2026. Trent Arnold and Vince Serwe built the company around something they already loved doing: fixing diesel trucks, heavy equipment, cars, small engines and everything in between.
In the first months of business, Arnold’s Diesel Repair had already written more than 50 repair invoices. Since then, the focus has stayed simple: keep investing in better equipment, keep learning, and keep giving customers another option when they need something fixed.
They work with individual owners, farmers, contractors, fleets, municipalities and businesses from Fond du Lac throughout Wisconsin. If it has an engine, hydraulic system, wheels or a trailer underneath it, there’s a good chance they’ll take a look.

Both owners are hands-on in the shop and out in the field. Customers can call either Trent or Vince directly.
