Thinking about buying Class C

Good luck with the Thor. We had a Dutchman by Thor. We had a awful time with workmanship. They had cut the roof to short to meet the sides. We kept seeing a wet spot on the pavement or a rare drip. We looked high and low. We resealed everything. The moisture soaked in and rotted the whole back end, because it just soaked into the wood and foam insides before coming out. A Thor and a folding bed are 2 deal killers for us. We got a 2016 Forest River which we bought on impulse without thinking it through. It has been great, but though for us a Class C would work better. That is why I was asking for everyone's input. I don't want to make another mistake. Thanks for your thoughts.
