Cold Bedroom

Thanks, Gerry! I'll try that. Yes, the furnace is in the living area. The bedroom would be the furthest point. It's also (from what I can tell) the only ductwork that is routed under the pressure. Makes sense it would be the least efficient. I have some airflow so I figured the ducts were at least partially in place. All the other vents are toasty hot and this one is ice cold. Just threw me off! I'll let you know how blocking the vents works out...

Thanks!

Not too uncommon........ Where is the furnace located relative to the furnace?
Mine is the living area and has a long run to the bedroom.

Try a couple of things.
Block off ALL vents except the bedroom, does the flow/heat improve?
If not, the ducting may have come off - check the ducting all the way between
the bedroom and the furnace.

If the flow improves then the ducting is probably okay; You then have to partially block some of the other vents so as to balance all the flow to each of the rooms. I did this putting duct tape to partially cover the vents closest to the furnace.

Been like that for years now and the whole camper stays toasty

gerry

Also, if the answer is loose duct work somewhere under the camper, how do I remove the coroplast protective cover?
