Have it narrowed down to either a suburban sf-42f 40000 btu or an atwood excalibur 40000 btu. Likely alright either way but if someone has a good reason to use one over the other let me know. Only concern with the atwood is the size of opening required for install. Any advice would be appreciated.
Which Furnace for enclosed Trailer?
- Thread starter ridinhard
- Start date
the main difference is that the Atwood furnace can be mounted vertically (against the wall). the Suburban's have to be mounted horizontally (sticking out into the trailer further). Both work excellent though. Hope this helps.
thanx Mikboo, do you know the size of opening required to install the atwood vs suburban? I like the Idea of mounting the furnace vertical.
I've got mine mounted vertically and the intake and exhaust are made out of abs pipe and a "U" bend exhaust pipe so they run up and turn 90deg. out the side through a 3"x6" piece of diamond plate .
Another factor to look at is the electrical power consumption.
You can go to the mfg web site and get the power consumption figures.
The Suburban SF35 uses 9 amps, while the SF42 uses 11.5 amps.
My vote would be to go with the lower power consumption furnance.

sorry, but i would have to disagree.......
seen it both ways, small runs all the time. loud, uses a lot more gas and electrical power. the 40 keeps it toasty and runs on a much more limited basis. air moving isn't an issue with mine. warm, quiet and uses less gas. .02
Why hack up a trailer?
I use one of these:
http://www.northerntool.com/webapp/wcs/stores/servlet/product_6970_200332747_200332747
Plenty of heat, good to 1000 sf, takes up little space and no holes in the trailer. No power needed.
I also use mine up at 9600 feet so I would take the 5000ft with a grain of salt.

oxygen sensored units can be a bit sketchy at high altitudes. know a few who have tried them and were not happy. how does an rv heater cause you to hack up your trailer? on small 2 inch hole in the side of mine. that and a few screws to mount, which you would need with this unit as well. .02 p.s. dizz.....we're gonna be pimpin' with the trailer this season!!
I have my tank on the inside it is only a 20 lb tank, I have 4 of them (use them for other stuff around the house).
I have had no problems with O2 cut out in a trailer, enough vents and air leaks (not like it is tuperware). Altitude has not caused any problems either.
The heaters I have sceen had a 12 x 24 screen on the outside and another hole for the exhaust. (maybe a diffrent heater/specks or size)
I like the vent free because it can be used other places when not used in the trailer. (garage, hunting tent, cabin, storage units, in an emergency) It can be hard mounted or free standing and no power is needed plus it is 99% eff. No vents needed totally vent free. It seems to work fine for my applications.
JMO and some other ideas.

If your going to do, do it right.
Dont order a smaller BTU to save some coin, there was mention on here to use a smaller one, thats just silly no matter how you think about it. Last thing I want is a furnace screaming trying to keep up, running its arse off.
What size of trailer ?
Here's what i've used, with awesome results.
14' long plus 4' V nose, 8'6 wide and 6 feet high (interior sizes), roof and walls insulated. Attwood 28,000 BTU furnace.
Now i run a 24' + 4' v-nose, 8'6 wide and 6'6' high, roof and walls insulated. Attwood 40,000 BTU furnace.
NEVER run your tanks inside the trailer, common sense will prevail on that one !! Also, dont run them on the tongue, you jack knife that trailer and your fuct. Spend a little extra and run an under belly vapour tank. I use a 14" x 40", full up at any Auto propane station. For my new trailer, I just ordered the same size.

Darko had the set up I liked when I did mine. The old forum had some great threads on this.
I used a 40,000 btu Suburban so I had a smaller vent instead of the door cut out. Side mount would have been nice. The Interstate has enough room it hasn't been a problem.
The under trailer propane tank has worked great. You can find one if you search around. I found mine used on craigslist $50.00.
Do a forum search on the subject. Here are few links.

I posted a WTD ad on craigslist with this picture. pay up to $100.00
Mine came out of a motorhome I had it checked out a local propane supplier.
Try it with your new trailer Darko.
