I've had lots of defects over the years, and in every case but one the manufacturer was prompt in addressing the problem at their expense...except for one company. Kwikee is the notable exception. They don't even HAVE a customer support number.
I had a 2008 Winnebago Access 31c. The Kwikee power step was not operating as per the instructions, and the defect eventually fried the chassis battery within a year. They digisync power slide was also manufactured by Kwikee. It died in the middle of the second year. Had a forum like this existed, I may have had some leverage with the dealer to have the problems fixed. Or better yet...I may have avoided that product completely. Great idea to start this thread!!!
