Wife and I just bought a New 2013 Montana Big Sky Model 3750FL.
The one with the Living room in the front of Coach.
We bought this last Oct when weather here in Florida was cooling down. At that time we noticed it was a bit warm in the front of this model but that became more evident as the Florida summer months came.
The front and Kitchen has a 13500 BTU
We went back to Dealer many times and they said all is working OK but it is so uncomfortable in the front of this unit that we can't enjoy sitting in our living room. So to us it is not OK.
We have fans constantly blowing to try and cool it down.
The back of this unit has a second AC unit 15000 BTU. it works fine and from the bathroom to the bedroom it is very cool.
I was wondering if any one has had this problem before with something similar and what you did to resolve. The Keystone company will not do anything their words are it was built as designed and the Dealer will not do anything they said the AC is working fine.. its either poor Duct work or poorly insulated. it is a all weather Coach. or at least that is what is advertised. We love this unit but we would love to sit in our living room more
