How 4-season are 4 seasons Lances?

4 seasons. Summer in Minnesota, spring and fall almost anywhere and winter in Florida. It will work in all four seasons.... as long as you use the wheels you have it mounted on properly.

There's a lot of truth to this statement. I don't think Lance ever intended there TC's to be used in artic weather. They are a beautiful camper and I love mine but survival was and is not in the 4 seasons plan.
Now, OP I'm commenting on my Lance 1181 and have no idea how your new 1172 will be as far as cold weather. My Lance did well after several upgrades that I got ideas from here on this forum and LOA.
There are six big holes in my camper. Large skylight over the tub, Exhaust fan over the stove, "dampener is useless". The Roof AC. The escape hatch over the bed. vent in the bathroom and kitchen area. Everything at camping world worked but increased the humidity by a lot.
Exhaust fan over stove. I taped some Styrofoam insulation over the outside after I wedged out the design of the outside vent. It worked!
the bedroom. I placed bath towels above the retractable screen to insulate and absorb moisture. This worked great until it broke the screen. Then I supported the towels with a simple dowel system used with shower rod holders. You'll have to replace the towels once a day before bed or they'll drip. Wring out the wet set and replace with dry, rinse repeat...
The tub skylight had an existing snap curtain that was hefty enough to support a nice chunk of the pink or blue Styrofoam. I leave one side unsnapped and the moisture will drain. This has never been a problem.
The AC was easy as well. I pulled off the bottom cover and stuffed some of these

up through the opening and reinstalled the bottom cover. Worked great!!!
The two remaining roof vents have ceiling fans. Not much worked here so I also put some of the expanding foam in the dome on top and didn't mess with it till I got home.
Every other opening was covered with the blue insulation board inside the door. Water inlet, propane, both flip up storage doors, etc...
All of this stuff works well in Florida where I now live without stuffing the AC box off course.
You'll more than likely have to push heat to the bedroom and storage tanks with some kind of fan.
I have much much more but it will all be covered by others. I lived 25 years in Binghamton NY and know your part of the woods.
