I think the Surveyor brand is as good and bad as well others out there. They have very nice features for their price point; however, I don't think the quality is any better than a really cheap trailer.
If you go into it knowing that you'll have to turn a screwdriver to fix minor things it will be fine. If you wait for the dealer on every little detail, you'll never have it on the road.
Not Surveyor brand specific but the two major issues that we've had with our trailer are:
1. The fiberglass front cap has a small spot on the gelcoat where it has spiderwebbed. My friend who bought his trailer a month after me also had this but the gelcoat cracked side to side. To date, Forest River has not stepped up to help out on any repair.
2. The welding one the trailer frame itself is garbage. Again, not Surveyor brand specific, Lippert manufacturers a majority of the frames for the travel trailer industry. In my case, the spring hanger tore off of the frame due to poor welding from the Lippert factory. Again, Forest River and my dealer did nothing to help. Going directly to Lippert's warranty department with opinions from 2 expert welding shops, they covered $6500 to remove and reweld the entire suspension back onto the trailer. I still need to report it to the NTSB.
My suggestion is buy whatever trailer you like but be sure to put it through its paces. We put 4k miles on it in the first year and saw these issues. Now that it's fixed, it'll last forever.
