Same here...double wide on a full foundation. Axles and tongues removed and on a full foundation is considered a permanent residence. We picked and ordered our home based on several standard structural specs etc that are typically considered upgrades with some manufacturers. 2 x 6 exterior walls, 2 x 4 roof trusses, floor joists, heavier subfloor, windows, furnace, on and on. Well insulated and go through about 1/3 of heating oil each year compared to most people i talk to with standard built homes of roughly same square footage of living space. Built and moved in our place 21 years ago. We did have 1 leaking skylight and replaced skylights, and replaced shingles with metal roofing while adding on a 10' x 17' front porch last year. Otherwise no leaky pipes or any other issues. Still going strong. Starting out it was what we could afford at the time. In a few short years when the kids are done with college and out on their own and its just the wifey and I here again, it will suit us well. Much better than an oversized and mostly empty house. Also, when we are old and frail, everything we need is on one level and won't have to battle the stairs for daily routines. Otherwise the basement can be easily accessed from ground level on the backside of the house if needed.
