I can recommend Redlands Truck and RV Service. They may be interested to helping you out. I used them for about 12 yrs now and my sister has has many mods done to their 42 ft Beaver coach. They are just off of Interstate 10 in Redlands, Ca (60 miles east of downtown LA).
Call Keith (owner) or Mike or Chris at 888-249-0124 and tell them "Duner" sent you.
Good luck,
Bill
