I have a 2015 fleetwood discovery 40g.

I was having problems with my  zone 1  furnace not  heating.

After some searching and a  technicians help a furnace valve was replaced and with some more  searching we  found that the flexible (rubber) lp gas line was  pinched  between the  drivers side  slide and the  exterior wall. Slide was retracted and the line was  tied up so it  would not  get pinched again.  Because this is the first time we have needed heat this year  we have no idea how many times the  line has been pinched  with the slide going in and out. Right now the furnace is operating  but  only putting out  a low heat and will not heat the rv properly. The technician feels it is because the line has been  pinched enough times that it is not allowing  enough  gas to the  furnace. Am i on the right trac and is this  something that Fleetwood should repair as a design flaw??

This seems to me to be a serious flaw that could have been catastrophic had the line actually ruptured with out us knowing.

I contacted fleetwood  directly and got a customer service person. He took my information  and checked the file. His answer to me was the vehicle was purchased 28  November 2015 and it was now 4 years later. If this had happened in the first year  they would have  repaired but  now it is over the time and it was my responsibility. There was no option, my problem not  fleetwoods. I told him to make sure my complaint went on  the file.
