Holiday Rambler full wall slide issues

I'd call support myself....they should be able to tell you who made the mechanism (ie,Lippert, HWH etc) and then I would get that info to the dealer...do not rely on the dealer to do the right thing...do it yourself and if necessary have that support send you via email specs, etc and give to dealer personally...the fact that REV would let a dealer sell their product without proof of that dealer's training to handle it gives me pause...
