Information overload

Tape on a roof is not always a sign of a leak. I have used Eternabond tape on all my MHs before they ever got a leak as my ounce of prevention. If you plan on working in winter weather dual pane windows are great. Just keep the advice in mind from here. As an example, we have had everything from TTs, popups, and MHs (Cs & As), all the time since 1969, when we had a 1 mo, old and 2 1/2 yr. old. You have stated you have zero experience. We have all made some mistakes and so will you. From our past experience I will say the Class A gas takes no more gas than a large C and is also no different to drive after the first full day of driving. I can turn in a shorter circle with my 38' A than in my previous 27' C.
