Best furnace?

I bought my Scamp with no furnace because of the complaints about the noise and smell of the cheap Suburban furnace that Scamp uses. My Wave 3 catalytic heater has been OK but I will not sleep with it on. I really want to extend my camping season, so now I want to put a vented furnace in the camper this winter and I am looking for something better than the cheap Suburban NT-16SE Furnace that Scamp would have sold me.

I want something that is easy on the battery (under two amps). Also, I think the 16k BTU of the Suburban is probably a bit too much heat (I don’t plan to be out in sub-20 degree Fahrenheit weather). I think that 6-12,000 BTUs is plenty and would result in less frequent cycling.

Option one is a ProPex furnace. I have done a lot of research on the SH2211 (6,500 BTU. 1.7 amps). I am sure I would be very happy with it but the installation is proving to be more difficult than I am comfortable with. The reasons are quite involved so let me just say that it is still on my list but I am leaning toward the traditional style of RV furnace.

Option two is the supposedly quieter version of the furnace that Scamp uses, the Suburban NT-16SEQ Furnace. I’m not sure I would be happy with it but I have not seen one in person.

Option three is the Atwood 8012-II (7900 series). This looks like a winner. 12,000 BTUs, 1.8 amp draw, a quieter squirrel cage blower and an easy installation. Nearly perfect except that apparently it has been discontinued and the replacements draw 3.4 amps! (Dear Atwood, I’m trying to extend my off-grid time, not shorten it!)

So finding the best furnace for a small fiberglass trailer is proving to be more difficult than I expected. Most of the furnaces made seem to be for bigger rigs, or they are entry level models that leave much to be desired.

So what is the best furnace for a 16 foot Scamp? Is it one of the above or did I miss a better option? I’m open to any other suggestions (except for using a cube heater when on shore power.. that’s a given).

I didn't know that the furnace in my Scamp is noisy. Damn, maybe I will not be able to sleep in the Scamp with the furnace on on my next trip...

Then should I conclude that you believe that the Suburban NT-16SE Furnace is the best available option?

You can pick up a new NT 16SEQ from Amazon for just over $350. It is the same size as the NT 16SE just a quieter fan and motor, and it fits a Scamp. I did a little shopping for slide in campers this summer. The new slide in campers were using a furnace that was smaller than the Atwood or Suburban you mentioned. I meant to research it but gave up on slide in campers. There are two slide in camper dealers in NC. One in Apex the other about 30 miles north off of I-85. If you are close to either you might want to go by and check them out. Sorry I don't have any more details but I have not seen the furnace on line.

Thanks for the lead.. is it Apex, NC New and Used RV Dealer €“ D&H RV Center ? I can call them.

Looking through their online ads, I only seem a generic reference to a 30,000 BTU furnace.. thats sounds crazy for a little truck camper!

It does seem like there should be better options, or that Atwood should not have canned the 8012.

The term "Noisy" is very subjective. I'm married, all my life is noisy

Not in the market, so I wasn't paying that much attention, but I think there was a thread on the new Atwood furnace on the Escape Forum. I think your concerns are for naught, but best you search the thread yourself.

D&H is the dealer in Apex. The other dealer is a bigfoot dealer. I looked again on line but did not see the furnace I saw in the slide in campers.

I installed the atwood II in my Scamp 13. It works well it has noise an you get use to it. I would buy it again knowing what i know. It works well at 9000 feet elevation but dont use the mechanical thermostat and use a digital thermostat.

While there may be nothing wrong with it, I am sure it is not the best option and I will not be buying one, so in this thread we can discontinue any discussion of the base 16SE model. The newer version (16SEQ) is still a possibility however.

I am also wondering if, with the Atwood side vent option, would it be worth the effort to add ducting that goes through the bottom front of the cabinet to the floor level. I think this may make it quieter and also improve heat distribution somewhat.

Just a heads up folks, you can change out the fan blades in the NE12se, 16se to the new fans from the 16seq. Lowers the noise level quite a bit. If you want it even lower then change the motor or use a voltage regulator or PWM to slow the old motor down a bit. The new blades more a lot more air. The 2 blades are cheap under $15 for the 2

Here is my write up without pictures, (sorry the one with pics is too large to attach) PM me for a copy.
