Atwood furnace for wheelhouse?

[low277]

I am new here and have questions about heating a 6'4" x 12' with a 3' v wheelhouse. I have been looking at Atwood RV furnaces, specifically the Everest 7920 II or the Excalibur 8520 IV. Does anyone here have any experence with these?

Is 18,000 - 20,000 btu/input enough? Anyone know how efficient these are? 70%?

Comments/Suggestions?

I am about to take possession of a Miltona Blacksmith trailer and am eager to get started.

Thanks

I got my frame there also 6 years ago. I have a 16k btu and my house is the same size but 7' wide. It stays as warm as you set the thermostat. I had the house foamed and the furnace runs 3-4 times an hour at -10 to -20 out. I am not sure on the efficiency of my atwood but a 20# tank will go 2-3 days in that temp range.

Thanks for the info! I am leaning toward a Atwood Everest 7910-II but have concerns about mounting. I have seen similar units mounted in the center of the V front but wondered about how the exhaust ducting was done?

Has anyone installed one of these in their house? I found on the companies web site that they can be mounted inside a cabinet and the front can be blanked and you use the two side ducts, this would allow me to mount the unit so the exhaust would be square with the wall of the V and run the 2 ducts to the cabinet front near the side walls.

Also how much air does the fan move, is adding 10 feet of duct and a couple of 90's a option or will the fan not be able to push that far?

Any feedback?

Thanks

The back of your unit butts up against an outer wall. You mount an exhaust/fresh air intake plate assy to the outside of your house. The exhaust tube of the assy is on the inside of your house, slide the furnace onto the exhaust tube. I have my atwood ducted out the front hole of the furnace and it blows hard enough to move the curtains around. I ended up putting my duct in the center of the front cabinet under the doors. I used to have the ducts on the sides but I also had my holes nearby on the corners, it kept melting the snow around my holes letting in cold air.

I have an Atwood 7920. Does the job real well. Had a few problem though. After a time trying to figure it out, found that it was the requlator. The cook top would burn, but the furnace would not fire. I carry a spare regulator with me now. Also make sure you have an extra battery, or a way of charging the one you have. On a mild day (0 degrees) I can get about 24 to 30 hours on a single charge. It does like to use battery.
