Wiring is the major thing to examine before purchasing an used trailer. Trailers built in the 70's or before could have serious wiring issues.

After a period of time, let alone moving the trailer, these wires can snap or crack making them a serious fire hazard. Have an electrician check the wiring in a mobile home you're considering - it'll be worth the price he charges.
