I use Good Sam VIP. In 2013 I ripped off three compartment doors on a 2005 DP. VIP was transitioning from GMAC to National General then. Long pole in that tent was the really long wait for the doors to be manufactured. Took over five months for the work to be completed. Rig was could not be driven. Timing is everything. New model year production was taking up factory resources and we had to wait for a lull in the line. I was told that dimensions change enough almost every year to make it impossible to find parts like this in stock. Winnebago claims to be able to do this much quicker due to sheer numbers and computerized control. Hope I never have to find out.
