I love love love my PUMA 30DBSS. We have had very little problems with our trailer and we are heading into our 4th season. We camp 4 days a week from mid May to as late in the fall as we could go before it is too cold out. We also travel to different camp grounds every weekend (most within a 150 mile radius).
Like the another person we had a problem with one tire that wore different than the other. Called our dealer which was 1100 miles away and he had not one but two delivered because he didn't want the tires to be wore different on each side. Also during delivery one of the tire panels broke from the screws, he again had two panels delivered within the week. (we only needed one).
Our local Forest River dealer will service if needed but they did tell us that their customers get priority on service. Hope I don't have to find out.
I would also like to mention that I have two teenage sons who are both over 6 ft and one is a little on the hefty side. The interior of this trailer has held out extremely well considering they are not the most graceful boys in the world. As a matter of fact the interior is still looks like new!
