4 season camping

Helping my daughter look for a trailer. Looking for a true 4 season unit. We went to the RV show last weekend in Tacoma, and she is impressed with the Arctic Fox and Outdoors RV. Intended use will be the Washington Coast in the winter, and also at the local ski areas, in addition to the usual better weather camping. She can buy new, but I have suggested she look for a used unit. The 2020 Arctic Fox 25W is her current favorite. Whatever she ends up with, she would like to keep the overall under 30 ft. Can you folks suggest any other brands or lines to check out?

In the PNW I would go with your DD likes of the North Woods units Arctic Fox is well known for 4 season builds.
I am very interested in them, and will likely do a factory tour in the near future.
We full tile in the PNW, both on the coast and Willamette Valley, have seen temps in the high teens in our three season Keystone Copper Canyon. Has heated tanks, and I have enclosed the belly, but we still have less than great insulation.
That said we heat with RV Comfort System "Cheap Heat" and it never was taxed keeping us warm (68 to 70 degrees).
So at 5,000 watt of heating we get 17,060 BTU, our gas furnace is rated at 30,000 BTU input, assume 80% efficiency is 24,000 BTU, so I can go colder by switching to gas.
We are two to four years from upgrading our 5er, will likely be an AF when we do.
