Speaking for full heated trailers from what I saw.
I saw a fully decked mission, and it was nice, fit and finish not as nice as a charmac. didn't look underneath.
looked at the Alcom sno Pro. thought it was ok, inside was pretty plain jane. crawled underneath and thought structurally looked a little sketchy in my eyes, as in light duty. holes drilled through square tube with u bolts holding the Axles on, frame looked minimalistic from what I saw.
Trails west interior was Tons better with the heating and drying set up, but disliked the rust on the underneath frame and the slanted floors for me I didn't like as well as the only 20' or 28' length options I disliked. I am looking for an in Between Length like 22'-24' range.
I liked the Charmac tri sport a lot and you can get it in steel or Aluminum, and order it in any length you like +2 foot at a time. it was nice inside, not as many features as the Trails West, but still functional.
my friend has a 17' 1999 or so Aluminum Charmac and it has held up very well being used a lot, with only rebuilding the Plywood floor. it did not have full heat or cabinets, but structure is still Sound.
just my opinion anyone else chime in??
