mntguy, Thanks for the Welcome.
The ducts are in the floor and it does heat up the trailer although it seemed very slowly. The furnace is under the bed in the rear so the bedroom are has more flow and heats quicker. I have no adjustment on the vents so can you cover or tape them partway too control flow?
My older Jayco blew harder and seemed to heat up quicker, but it had a different brand of furnace and was smaller.
I have found over the years that a great wealth of info is available from every day users like you so Thanks for the Info and as a relative Noob I'm sure I'll be asking more.
I live in deep South Texas on the Mexico Border so our mountains are the freeway overpasses
