I have a Montana 3605RL fifth wheel and after checking out the routing of all the hoses and ducts and evething else, I have noticed a 2" flexible heat hose which seems to go down into the lower tank area, which I believe is used to keep the holding tanks from freezing. My question is, if I camp in weather 45 degrees and above, can I remove this hose from the lower tank are and either plug is off to increase the heat through the other heat runs or can I run that hose to somewhere where it would be more benificial to heat the living space ?? Seems like a waste of hot air where it is going now, especially sice I don't camp in the freezing temperatures. Thanks for any reponses !! Campingmike
