Coleman PUP no heater.

If you have AC, you probably have a 20 amp circuit to plug an electric heater into. Buy a heater that uses less than 20 amps and you will be fine. the 20 amp receptacle has one of the blades that is "T" shaped. You can also get a 10 or 12 ga. extension cord to run directly to the shore power pedistal.

I agree more so with electric. I'm a fire engineer by trade and I don't like the idea of an invented anything in the close proximity of my 5 year old daughter.

I've had two Little Buddy heaters going in both Pop Ups and tents. It's fine.

Never seen a pop-up yet that anyone would call "unvented"... despite the "safe for indoor use" rating, I, too, might think twice before using a Little Buddy in a closed-in trailer or RV.

A small electric heater will do the trick as long as you have 110 volt power available. I have used such a heater to heat my 24' travel trailer during spring/fall campouts. If you're rated for 15 amp on an outlet that gives you about 1200+/- watts available for use. A small heater set on 750 or 1000 watt will heat your popup. I do not like the idea of using an unvented propane heater in a small area while I'm sleeping.

Thanks for the tips!

I will be sleeping in my hybrid trailer tonight in the backyard.
Add Popup Gizmos and insulation in the window slots.
Get a good down bag and wear a hat. Add a quilt if it is cold.
Popups and hybrids are good to the mid 20s or so with no problems.
Just get up and make coffee in the morning with the gas stove and it is pretty comfortable. A Little Buddy Heater is okay but I would never go to sleep with one.

Very true on the not for long. I have a degree in HVAC technology and the second my wife said we I can just plug it in here. The electrical and heating side of me kicked in and said NOOOO. I just saw smoke before it was over with and I was told many years ago that once you let the magic smoke out of something you can not put it back. lol

From Pages 14 & 15 of the 1988 Coleman Camping Trailer Owners Manual...





PS: I should have clarified that we use the Little Buddy heater only when camping in the wild, which is most of the time. If and when we find ourselves camping in cold weather with the luxury of shore power, we have a small, quiet electric heater with an auto-thermostat and a heavy (orange) 25' extension cord.

As far as I know, they don't make an electric heater that would run through an inverter... at least, not for long.

That was the thought I had. I don't see the electrical system of the camper being strong enough to safely support the heater. I see that you camped in one of these for a while and I looked a little more closely to mine last night and it is also a 1988 sequoia. Do you have and tips and tricks to add about the camper. We had travel trailers when I was growing up and I am in the market for one now. We have camped a few times in the PUP and like it but we would be a lot better with a TT around the high 20' range. I want to make do with the PUP through this and next season unless the deal of a lifetime jumps at me between now and then but I don't have a lot of experience with this one.
