While we were in Myrtle Beach I stopped at Camping World and spoke to a Service Manager about issues with RV's in general, the Manager told me that there are NO regulation when it comes to RV except the axles. RV are considered as luxury units, so the manufactures can do what they want. One would think that an RV would fall under the automotive standards, but no they don't. Everyone has a sticker next to a door on the out side of there camper, it is a RVIA Cerification sticker with a serial number all I can say it looks good on there. This may be the reason most people have some Issues with ther rigs, they pay alot of hard earned money for units that need repair after the warranties are up after a year. Some of use have no problem making mods and repairs, but some have to rely on the service department. There is a lemon law that can protect you if it gets out of hand. Like the Service Manager said, if there were standards set then most of the problems would go away. Best of luck to those you are having a tuff time of it, I have been there my self.
