Propane Switch & Furnace Questions

Hey everyone, I just picked up a 2006 Cherokee 23DD. Have a couple questions for you.

1.) I am smelling propane coming from the front propane selector switch. I took the cover off it and noticed there is a vent on the bottom. Is it always venting propane? I sprayed the switch with soapy water and if I plug the vent with my finger on the bottom (Circled in red) it starts to bubble at the top of the switch where I also circled in red. Basically meaning there is always something coming out of that vent. Do I need a new switch?

2.) How much air pressure / volume should the furnace motor push out of the three air vents on the floor? When the furnace runs I can barely feel any air coming out of them. The trailer still heats up, but there is definitely not much air flow coming out of them at all. My old trailer was a small hybrid, and although it only had one air vent right at the furnace, it blasted it out. This trailer barely seems to push any air out.

Shut your tanks off NOW. imo, Your regulator is leaking and should be replaced.

I agree with Brother Les... that tank selector/regulator is bad and needs to be replaced immediately.

As to furnace airflow, you should gain access to the back of the furnace and check that the plenum is closed up tight and that all the flex duct attachment fittings are properly in place. On my new 5er, the screw on one side had fallen out and the plenum was half open. Also, one of the duct bayonet fittings was almost off. Hot air was mostly circulating in the utility space with very little going out the farthest registers. Much better now.
