The floor plan I liked had a large acrylic skylight.
Owners were complaining about the skylight allowing too much heat build up, making the interior too hot to cool. The 13,500 did not handle it and people swapped it out for a 15k which helped very little.
The fix is in that design or opt for an additional a/c making the 50 amp upgrade not a cost effective option.
It was a rear slide model with no place to install a rear ladder to access the roof.
Some of those Thor products mentioned did not have the radio antenna connected and it was very difficult if not impossible to gain access to connect it once the unit was built . Some had to re-drill and install new.
That kind or lack of quality control is just not acceptable , so I cancelled my order and went with the Sunseeker of which in my case, im very happy.
The few issues I had were dealt with by the dealer and FR with very little down time and for me, that's the name of the game. Being able to actually use the RV that I purchased instead of seeing in parked at a dealership waiting for a fix. Been down that road for 3 to 6 months at a time...never again !
