I will make a recommendation. Alfateeers RV Service Center in Fontana, Ca.
When Alfa went out of business they formed this company using many of the Alfa employees. I met these guys at the Pomona RV Show where they were showing a 30' bumper pull trailer they built from the ground up. Very impressive workmanship. Subsequently, I had my RW in for 4 days where they painted the front cap, reinforced the fenders, replace the curved wall to the BR and repaired the wood trim on the curbside slide.
They also have 4 electric & water hookups where you can stay in your RV at night.
