When we went to the Seattle RV show this year, I was disappointed in what I saw in TT's and fivers.
While in some cases the materials and technology seem to be better, it is always badly offset by lousy workmanship. This goes for all the big manufacturers.
When someone says their brand X RV has been great you can't even count on that because it's just one sample. For instance, My Forest River has been great but their quality is average and I think I've been lucky.
I'll get some heat here but even the more popular brands or models like the Montana, Cedar Creek and Jayco products are sorely lacking in quality and fail in the simplest executions - but they are not the exceptions at all.
I wish there was a brand to suggest but they all need to make huge strides in craftsmanship. Somehow they need to get their management and assemblers to care at least a little.
