I just moved away from home, which was a trailer that that had it’s origins in the 70s, so it’s nearly 30 years old or more. Frankly, those things aren’t meant to last that long. In the past ten years, all the floors have been replaced, except for one room, which is going to get that treatment shortly. The floors were particle board and that rots like crazy, even with the semi-drought conditions that have been building for the past few years. Same goes for the roof. Ours was replaced this summer, because a hail storm the previous summer banged the all-holy hell out of it, but the effects didn’t show until after spring thaw. In March, the living room suddenly had an ENORMOUS ceiling leak, but nothing could be done about it until after planting. Such is the lot of the farmer.
The walls are very thin and sound travels across the entire trailer. When someone’s watching TV in the living room, you can hear it in my parents’ bedroom and vice-versa. This also means that, um . . . my room being next to my parents’, sometimes I heard “sounds.” We’ll leave it at that.
Anway, it’s a double-wide and, like pepperlandgirl, six people lived in it. I can imagine two people being comfortable, but six? ACK. 'Twasn’t shibby at all. Trailers, in my experience, are pretty compact and there isn’t much storage space. You might want to think of “creative” storage solutions if you can. Also, the doors on ours are slightly narrower than standard door frames, so you might want to measure any existing furniture carefully, before going to the effort of hauling it to the new place and discovering that your sofa won’t fit. The ceilings were low enough so that 5’2" me could palm my hand against them with very little effort.
As for leaking heat and A/C, if you seal the windows with plastic (3-M makes kits), it reduces the loss significantly. If you stretch it good and tight, you can’t even tell the windows are covered. Curtains help even more, though more so if you keep them drawn. We did this and the only drafts came from people leaving the front door open.
One of the main drawbacks is that there isn’t a cellar, so when there’s a tornado warning, you start thinking frantically of where the closest ditch is and hope that your dog isn’t kidnapped by the evil spinster schoolmarm.
