I use the Buddy and love it. It's also available from Lowes. Only difference is the color is yellow instead of red. Price on the shelf was a few dollars less than Amazon. As noted it does produce a lot of moisture, so the cracked window/vent is a must.

Super busy these days so sorry about the delay.
In my opinion, the Little Buddy (we have the Portable Buddy) should heat your TT just fine. However, if I were you I'd go pick one up at Lowe's or HD so that if it doesn't quite do the job you can return it easily. It will definitely work fine if you move it around to where the 2 of you are - dinette, bed, batbroom, etc.... I just don't know if it will heat the entire 1985 evenly.
The reason we have the Portable Buddy is because of our previous larger popup trailer surrounded by canvas. Our 1575 heats up quickly even with our single tent-end (that does have a solar blanket on top & Reflectix in the windows in cold weather) so the Little Buddy would work for us.
Another reason I like the Portable Buddy is for power outtages at home. It will heat our master bedroom or kitchen or family room nicely while we are awake. We've had to do that 4 or 5 times including once a few weeks ago.
One more thing - I do feel that the Portable Buddy is more stable than the Little Buddy for safety reasons.
And of course - whichever you buy, PLEASE DON'T SLEEP OR LEAVE WITH IT ON! 
I saw the review comments about the limited stability of the small unit after the bottle is empty, so I added a larger base to my order. It looks like this one.
Nice Kent.
I have one of those for a single burner stove we use. Very stable.
Be sure to check back in and let us know how well it heats up your trailer. The whole trailer, localized areas, ...
We use the buddy every once in a while. I prefer the Lance heater but the buddy works well. Humidity is the biggest problem and inability to thermostatically control the unit is the second problem. Vent the rig and you should be fine.

Of course we all use our furnaces, but the Portable Buddy (or Little Buddy in Kent's case) comes in handy while dry camping &/or boondocking as far and away the number 1 power draw is the furnace fan. Not to mention the furnace is noisy while watching a movie, playing a game, or someone is trying to sleep in.

I do agree there are times where the Buddy comes in handy, however, because of the moisture that the unit produces and the headaches I get when I use the device for extended periods of time, I only use it when I am very low on LP, or during an emergency. I personally don't like to use the Portable Buddy in general use. Just me. I don't know if I get a headache because I think I should or because there is a justifiable cause.
$104.99 is enough to give me a head wound.
Only $79 at Lowe's, if you don't mind the yellow. Mr. Heater Buddy at Lowe's
As its getting near the end of the season they often put them on sale too. I think I paid around 60 at lowes for mine.

Sorry to hear about the headaches. 
That doesn't happen to us (plus we leave a ceiling vent cracked as well as a tent-end zippered window open a crack).
Quite a few places have it in the mid $80.'s right now -

Nice find LJJ!
I just checked. We have 2 stores in this area. One of them has them in stock (not that I need a second one though).

I find I can get about 5 hours on low on a 1lb bottle. It actually does not produce carbon monoxide but carbon dioxide so if you keep things closed up it gets damp inside. We do crack a vent or window though.
When everything is setup for perfect combustion they makes CO2 and water vapor. They all make carbon monoxide when/ if they run low on oxygen. Like if they use it up when not vented enough.

We recently took an 8 week trip out west and spent approx. 2 weeks in the Quartzsite & Lake Havasue areas on BLM land.
In was quite chilly at night necessitating heat. We supplemented our furnace with the Mr. Heater Buddy. It worked great.
In our truck camper, we found a perfect place to use it! We lowered our oven door and placed it on that.
It was off the floor, in a spot made for heat. It functioned like a little wood stove, as we could snuggle up to it and warm our hands.

I don't know why I've never done this before a couple of weeks ago. I did the same thing, set my Big Buddy on the oven door, works perfectly!!
Ran it on Med. (9,000 BTU) and it quietly heated up the 1685 in no time without the drain on my batteries from running the furnace.
FYI, I haven't bought any 1lb. propane bottles in ages... Refill them for next to nothing.
Tip: Put the 1lb canisters in the freezer, and the 20lb tank in a tub of hot water and you can get them very close to storebought full.

i have the buddy convert hose so i run the 15lb bottles, this spring putting a quick connect below the oven hooked onto this side of the regulator so i can use my outside bottle on the buddy heater. https://www.academy.com/shop/p...repChildCatid=467906
I bought 3 of these refillable flameking 1 lb cylinders and made this refill jig. No dickin around with freezing and a full fill each time. I ordered from home depot online and picked them up at me local store. I have refilled the disposables until I overfilled one and in the heat it assumed an hourglass figure. Not pretty.
