A generator is a very good thing to have whether portable or built in. We are fulltimers and started with Honda portables. Since we have a diesel truck, we found it inconvenient to carry a fuel we only needed for the generators. In an emergency with wide spread power outages, we had to drive miles to find gasoline and of course, there was always the worry of the generators being stolen. We had an aftermarket Onan 5500 propane generator installed. We found an excellent price on line and had it drop shipped to our manufacturer and later installed at a much lower price than an install at build. We used it quite a bit on our recent trip to Alaska. We stayed in Denali National Park for 6 nights (the limit of our fresh water) and that was possible only because we had a generator. Solar would have not worked because it was heavily treed. The use of a generator has opened up a whole different camping experience for us because we now stay at many more places without hook ups and for a much longer time. By the way, we did not find that our generator sucked great quantities of propane. We only had to fill a tank 3 times on our entire trip (4 1/2 months) and that was for all our propane needs including heat. We had to balance the loss of storage space with the addition of a built in generator with the generator winning out. Portable or built in, they are a good thing to have.
