Hello Captn' Steve - Although not in SW Florida, Alliance Coach up in Wildwood, FL would be a recommendation. They are authorized dealer by Source Engineering to install the replacement trailing arms for the 4R4 Roadmaster chassis along with the ride improvement kit by Source. I have read on IRV2 that they do good work. Stay the heck away from Camping World and LaMesa, as they hire "clowns" (i.e. not very well trained) to do service work.
