Thank you all for your replies and suggestions about the heaters for the Overlander. Sorry to not get back right away.
The exterior is squared away and sealed so now I can turn my attention fully to the plumbing and furnace. Fortunately a good friend of mine who is a General contractor/ electrical contractor (and a very good plumber to boot), said he would take the lead on doing this part of the project. So I can be his assistant and learn.
I have a couple of questions to throw out there:
One is regarding the tub and bathroom sink piping. If we am going to run pex all the way to the tub and sink fixtures, will I have to remove the fiberglass tub/sink structure to access the fixture connections properly? Don't have a problem with this if it is the best way. I suppose for thoroughness sake the copper should be replaced all the way to the fixtures and not just simply attach the new pex lines to the copper lead lines going into the fiberglass tub/sink structure. That would be easier but it would also be a potential weak spot. Opinions?
FYI...There is no toilet now and I am not going to put one back in but going for the Thetford Porta Potty a la Touring Dan's improvement (http://www.airforums.com/forums/f116...s-94152-3.html
) The old owner hacked the fiberglass toilet seating structure in half but the tub and sink portion is good and I want to preserve that.
The other question I have is about the Univolt 30 that is still functional and in the trailer now. Would now be a good time to replace it? Or does "if it ain't broke, don't fix it" apply here?
Again, thanks for everyone's interest and suggestions. It's great to have other Overlander owners and their experience as a resource.
