Mechanic in Tampa Bay area?

I have taken my RV(s) to Camping World over the years because of the following reason: When I am on the road and a problem develops, I take it to the nearest CW if available. I did this many years ago when a leak developed in my black tank valve. I took it into CW, had it fixed and continued on my journey. Two days later and several hundred miles from the original CW, the leak occurred again. I took it into the nearest CW, explained the problem and they had it repaired correctly with no charge. If I had originally taken the RV into an independent repair shop and the same problem occurred I would have no recourse but (1) taking it back to the original shop or (2) having another garage fix it...and charge me. That's the main reason I am a firm believer in CW.
