Can't comment on the right insulation; but can empathize with issue from a new coach. I recently dealt with Forest River on our new coach and although it was a huge pain, the end result was that they took our coach back to their service center and corrected a long, long list of issues. The person I worked with was very helpful and communicated well by email. Due to the amount of time that our rig was out of use, I even convinced them to pay my monthly payment. I have a post on here with the details, search for "2011 Georgetown 350TS"
Short update on the Georgetown. As I stated in my original post, the dealer has really done their best to fix the items. They made arrangements for the unit to be taken to the Forest River Service facility in Indiana for a complete review of issues and repairs. Happy with the pressure the dealer put on the manufacturer and how everyone responded. They have had the RV for the past 3 weeks and I'm expecting it back next week. Due to the amount of time the RV has been in service and unusable; I requested they also make my July payment, which they did.
Fingers crossed for good results, we are ready to hit the road again.
It's good to hear that some of you have had good luck with your coach's. I dropped mine back off at the dealer again yesterday with another list of items for repair. Since my original post and covering a few miles; we spouted a nice hydraulic leak and the refrigerator would not cool down below 44-50. As Traveller stated, I expect to fix a few items on a new coach, all of my previous rigs were new as well but the number of items breaking is just unacceptable.
We had quite the toad issue having 4 smaller children (6-10) Ended up going with a Jeep 4-D Wrangler and buying a 3rd party jump seat for the back. Tow's great and the kids argue over who gets to ride in the jump seat. Purchased it from a company called Little Seats http://www.littlepassengerseats.com/ Pretty easy to install and has a 3-point seat belt. Works well for us. Good Luck.
Just have to vent a little. I've owned several travel trailers, a Coachman Class C and now the Georgetown. The number of issues with this new Georgetown is more than all my other rigs combined. I have a good local dealer and they jump right on the issues; but the total number of items fixed is staggering. Left today on a 3 week trip and the camera system jumps through all 3 views every time a blinker is used, the leveling system seems to be way off calibration again and the toilet will just trickle during a flush. Individually none of these are insurmountable; but since I just picked it up from the shop again this week, the frustration is peaking. Really don't think this is representative of all Forest Rivers; but one has to really question the quality control. Now off to fix the toilet....
