Looking to have used Coach Lift chair installed

.

Assuming you're not capable of making the necessary mods yourself:

Plan A. Call the mfgr. Explain your "problem". Ask if they have any solution.

Plan B. Keep calling / trying independent RV repair businesses and mobile repair.

Plan C. It's *not* necessary to use an RV repair business.
Try local handyman. (Bonus - May be more cost effective).

Good luck.
