Furnace in 260RLS

Recently picked up a 2013 Timber Ridge 260RLS. Been playing with it in the driveway. Impressed with everything except furnace output. Just took an hour to get the trailer from 50 degrees to 65.

Does this seem normal. The bathroom cabinet vent pumps a lot of warm air when opened all the way but do not seem to get much flow from floor vents. I turn the bathroom vent all the way down.

I have scoped the ducts for blockages but the scope is only about 3 or 4 feet long. Saw the round cutout on top of where the dump valves are to prevent them from freezing.

Only place I cant inspect is where the furnace duct joins the floor duct. Really dont want to drop the coroplast and I am not sure if I could see anything or if there is an issue at all.

Thanks, Jason

Welcome to the ORV forum:

The furnace output should be about the same on all registers. They are not wind makers by any means.

I found a disconnected furnace line to the bedroom. Clamp had not been tightened correctly at the factory.

Be sure all the roof vents are closed if you're testing this system.

I had the same thoughts on my 2016 F26 RDS, not much air flow on floor registers. Finally decided to pull the furnace to see if it was at the plenium end of things. The furnace plenium is connected to the floor ducts by a rectangular cutout matching to a rectangular cutout in the floor thru to the floor ducts. It had a 1/2 inch spacer of plywood between with a similar hole to level the furnace and some fiberglass insulation as a gasket. The spacer had not been fastened over the hole in the floor and had slipped sideways partially blocking the opening. After correcting it helped. Not a lot of air movement in the floor registers as far as I can tell, not like a house. I think that the spacer and reducing hot air loss with better gasketing increased the flow. No sense heating the basement too much. Removing the furnace a bit of a hassle, but by the third time it was much easier with less adjectives.

Thank you, I was just looking at the furnace today. Not a lot of room in there. Was trying to see how easy it was to remove. I think before I go that route I will disconnect the round bathroom duct from the side of the plenum and see what I can see with the scope.
Not sure there is a problem but seems to take way too long to heat the trailer. I boondock so having the furnace running a long time is hard on the batteries. My old 26 footer heated up quickly with just two round cabinet ducts. This trailer is a lot bigger but furnace has a lot more BTU.

I suspect your furnace and ducting is fine. I'm currently out in my 26RLS and the furnace takes about 20 minutes to bring the temp up 7 degrees. These trailers are really well insulated, so a large furnace isn't required to maintain a comfortable temperature. In fact it hardly ever runs even though it's 45 degrees outside. A larger furnace could bring the temperature up more quickly, but would probably end up short-cycling, which can cause reliability problems.

I don't have a cabinet vent in the bathroom, but the floor vent there does seem to put out more air than in the other spaces. As others have said, the air flow is pretty low, but it is hot. In fact that's a bit of a problem if you walk around in bare feet. I came close to burning my foot once when I stood on the vent in front of the stove.

Took a look at the plenum today. Took off the cold air return screen and then the front of the plenum. Noticed right away that the round vent tube for the bathroom was only partially connected.reached down where he passed through floor and found a very poor foil tape job. Lots of gaps where the plenum meets the floor and where the duct underneath connects to the bottom of the floor. Not much room with the heat exchangers hanging overhead. Went outside disconnected the furnace and pulled it out about a foot. With decent access the plenum I foiled all around the ducting. Seems to have added a bit more flow to the vents and more heat. Seemed to warm faster too.

I have now checked every inch of the system except the T where the duct from the furnace meets the duct that runs down the middle of the trailer.

Taking the trailer out for a few days tomorrow.

I have a 2020 250RKS and I found that the opening for the floor ductwork where it mates to the bottom of the furnace was cut out in the wrong place. it was off by an inch. Had to move the furnace back an inch and remount to make everything line up properly. Once that was done the trailer warmed up noticeably faster!
