1st trip, heater problem?

we went on our 1st trip with the new Puma this weekend. we learned a lot. the biggest problem was the heat. we camp up in the mountains where the temps get very low at night. The bedroom stayed cold while the rear bathroom was smoking hot. the floor has 3 floor vents, the 1 in the bath blows hard while the front has very little flow. Is this an inherent problem with the system, a warranty problem, or something I should fix myself?

Replace the vents with adjustable ones from Lowes/HD or a hardware store.

Had similar issue. Went to lowes and picked up magnetic vent covers. Cut to size and cover as much of the vent as need to slow or stop air coming from that vent. Only a$6 for 3 sheets

Your bath heating vent is probably closer to the blower, hence more air flow, than the other two. Like the above posts said controlling where the heat goes is your best option. We use the magnetic covers which we also leave in place when using the AC. Cool air falls and I see no sense letting cool air go into the floor registers.

thanks for your help. Am I right by assuming that this is not a forest river warranty problem?

Correct. It is a air flow issue that can be corrected with the solution Old Coot Provided

so I put in a closable vent in the bath today and it helps. I checked all the ducting with a small flashlight and cell phone camera,all clear. reading up on the heater, the 35 series states 4 vents required, and I only have 3 ?????? I'm thinking of just adding another vent at the stairs leading to the bedroom. BIG NEWS. the heater is in the very front and the bath is in the very back. 1st vent -least air, last vent- most air?????

Another suggestion: All the vents probably come off a common plenum at the heater. Can you get to it? If you can, you may see something odd there (I'm guessing). If a duct got twisted or something, it could be blocking air (I'm assuming your flashlight/cell phone could not see the entire length of each duct). There might even be some kind of adjustable dampers for each duct (I know houses have these, but don't know about 5ver's). Also, depending on what the plenum looks like, you might be able to swap vent ducts around on the plenum and get more air up front and less to the bathroom.

Another thought: The plenum may have "knockouts" for multiple vents; you knock out only the ones you use. It's possible they attached the duct, but forgot to knock out the knockout.

It is all one run. there are no off shoots. One square duct directly under the floor with 4x8 registers cut directly into the duct. the rectangular duct connects directly to the heater. all the 4" round knockouts are still in place and I was able to see the entire duct because I took the face of the heater off. thank you so much for the reply
