water pipes

Examine your water lines to see how they are exposed enough to be subject to freezing. Insulation and a heat tape to prevent freezing would help. Less seriously, consider towing the house to a southern climate.

Simple solution: sell the mobile home. They don’t call them portable ghettoes or tornado magnets for nothing.

When I read Richard’s response, I expected to see SylvanLMP’s name on it. You’ve done much better than that in the past Richard.

You might as well say “If you don’t live is a 13,000 sf $5m house, sell it and by something decent.” People live where they do for many reasons. Let’s show some civility to everyone using this forum, to other members and to those asking questions.

How about providing good answers if possible or asking for additional information if insufficient information was given in the question.

You may try a hair dryer, then installing heat tape/s to keep the problem from reoccurring. Also make sure your underskirting is in good shape. I would most likely not try a torch. Too much flammable insulation normally.
Good luck.

I forgot one important note on heattape. Do not allow the wires to cross over themslves. This can short it out in time.
