I really wonder how feasible it would be to get a heat pump for the old RV my husband and I are currently living in. It needs a complete revamping of the power system anyways, since it was made in the 90s and charges the 'house batteries' at a snail's pace. We plan to add solar to the roof, and if we can find a way to use the propane heating and generator less it would save us quite a bit of money... Heat pumps are great, and even if we can't get one for the RV, we plan to have one for whatever home we can buy/build in the next few years.
