I mainly wanted an idea of the wait time and cost. The staff was easygoing and straightforward. They explained it would be $85 to hook it up, check the levels, and then go from there.

I'd definitely come back and would recommend them.

I experienced what I assumed was transmission problems while driving through Fontana, CA. in Nov 2025. I was driving a 1999 Fleetwood Pace Arrow with the Ford V10 F-53 chasis. Good Sam towed me to J&L where it was discovered that my flywheel had broken. They jacked up the front end & backed the transmission off so they could get to the flywheel. in doing so they broke a cooling line and spliced it instead of replacing it. They installed the wrong flywheel then left a main transmission wiring harness unsecured which allowed it to fall onto my header and short out three solenoids in my transmission causing catastrophic failure. Additionally, the compression fitting that was used to splice the cooling line leaked so they shoved an O ring in it which eventually clogged the line causing further damage

Stopped in to get the pump and nozzles for wiper fluid fixed on my tractor. It was a weekday…read moremorning and they were able to pull me in and start working immediately. It took a little over an hour. Pros: quickly serviced me and quickly got me out of there in about an hour. Price on nozzles was pretty good. Cons: price on the pump was meh. A week or two later, the line to the wiper nozzle got disconnected because it wasn't long enough and there was too much tension when using the wipers. I had to reroute the line and secure it differently in order for the line to remain connected with regular usage. Really simple fix, but I just paid someone $300 to have my wiper fluid system in good working order. This shouldn't have been an issue... and my line is still pretty short. I just had to work around it. If I wasn't using the company card on a company truck, I'd have saved myself $240 and done it myself.

Terminaron entregandome la traila mediados de agosto 2022, y ya para septiembre tenía que darles el premier pago mensual de $2100. La traila no estuvo terminada. Le faltaba el aire no venía con nada de las cosas que iba a vender. E igual que al otro señor, a mi también se me metió el agua. La lámina se oxido. Nunca me dieron precio, resulta que la traila costó $80000 pero con el in house financing iba a pagar $140000. Comprar esa traila fue mi peor error $140000 por algo que no podía ni cocinar. La hicieron repo, y la volvieron a vender y el nuevo dueno se fue a vender a adelanto y resulta que le dieron tickets y estaban llegando a mi nombre. Fui varias veces a resolver el problema. Y la última vez Ricardo y yo nos dimos un agarrón verbal y le reclamé que nomas me engañó con la traila, y saben que fue la respuesta del señor? QUE TODO ERA POLÍTICA. Así que si piensan comprar traila asegúrense de no ir a ahí! Bien buenos para estafar a la gente y aprovecharse de la situación de uno. Que se puede esperar de ese gente después de enterarme como fue que inició el negocio. ESE NEGOCIO FUE CONSTRUIDO A BASE DE PURA ESTAFA!
