Check with La Mesa RV in Tucson, NOT any other La Mesa anywhere else. They should be able to do it. The Tucson location is one of only three places in the US I'll let work on my RV. I bought an 08 Bus from them new and have bought parts, had major counter top change outs and a number of other work done. I've been allowed to watch the work, ask questions and fully discuss the repair before it was done. I wouldn't trust the La Mesa in Mesa as far as I could through them. They flat out lied to me on one repair and then I had to re-do the wiring on a jack repair they were supposed to do under warranty. The La Mesa in Yuma just didn't strike me as being interested in doing any work, let along doing any job well.
I do all standard maintenance on my coaches and use dealers only for big complex jobs I cannot do when 2500 miles from home.
