been looking at tt s and most seem to be 11 ft tall but I seen were coachmen (don't remember which model) wre 10ft high. Do you think a foot less in height would make a big difference in towing
When checking trailer height, you need to find out if that is to the roof or to the top of the AC unit. This can also vary between the same brand/model of trailer depending on what AC unit is installed. A Coleman Mach5 is a low profile unit roughly 6-8" tall, while a Dometic can be close to 12" tall.
On average conventional RV trailers are ~11' tall to the top of the AC unit, but there are a few that can be up to 12' high. Easiest way is to check the manufacturers website and look at the specs there. Dealers tend to leave a lot of information out. Interior ceiling height can also give an idea of the taller units.
My Coleman 274BH is just a hair over 11', I have to remove the cover from the AC unit to get it in my barn, and just barely. The top of the AC clears the trusses by 3/4 of an inch.
Oh, and height wont matter much in towing. The truck will work just as hard with a 1' taller one as an 11' tall one. Length could play a factor, the longer it is, the more wind forces can play with it, but height, not so much.

You know better!! You throw that out to stir the pot?
I'll respond with a different take. My Jayco Jayfeather was 10ft tall to the top of the AC, but the ground clearance was lousy. That means when towing, you'll have to be careful on gas station entrances and exits. It also made for lousy flow from the black and grey tanks to the the sewer pit.
My Jayco Whitehawk is 11ft 4" tall, lots of ground clearance, no worries about bottoming out. Good flow from the tanks.
My Jay Feather was 5200lbs, my Whitehawk 8200lbs. My mileage went from 21L/100km to 23L/100km, abut 1MPG difference. For what I gained in trailer, it's worth 1 MPG.
ground doesn't show the height difference...camper (28ft) is about 8 inches higher with axle flip kit...the frontal area are about the same but the black one(22ft) tows like a brick....

Really? I don't have any TT experience, but with my enclosed cargo trailers, the drag impact was pretty obvious empty as well as full, and I always thought it was a frontal-area consideration—an empty cargo trailer was worse than an open sled trailer with sleds on it, and I think the weight was comparable. A foot shorter seems like it would be a significant decrease in frontal area and thus in drag.

I have this same issue with my JayFeather X213. I am waiting for the day I tear the black water pipes out when traveling down some rugged BLM road. I am sure it has been pretty close already.
It's not so much the height as it is the fronal surface area or cross section and yes, the surface area on the front cross section (leading edge) of the trailer has a dirtect effect on the air resistance.
Pretty sure this is why Frontal surface area is mentioned in the towing manual as well.
A pop-up tows much easier on fuel economy and air resistance than a full height TT. It's just physics
now, will you feel much of a difference between an 11 foot TT and a 12 footer? probably very minimal using a butt dyno. It may be exposed as tenths per gallon in fuel economy calulation.

That's the same trailer I had. I loved that trailer, but it was low. Now I have a 28BHKS, it's a nice upgrade with the kids getting bigger.
trailer height question?
