Welcome to the Forums and the world of Vintage Airstreaming!
The orginal tanks have some rust and we were wondering if we could replace them with regular propane tanks like you would get at Home Depot (gas grill kind etc.) and just update the fitting and hose?
Any help will be great on this or any other restoration hints.
Something else that you might want to consider is just what your future restoration plans might include. If polishing the exterior of your Bambi is something that you are considering, you might want to consider the feasibility of Worthington Aluminum LP tanks - - they can be polished to match your coach and are much lighter for routine handling than similar sized steel tanks - - my 40 pound Worthington tank is as easy to handle as the 30 pound steel tank that it replaced. I purchased my Worthington Aluminum tanks from AirstreamDreams.com
several years ago and had them polished just after purchase when P and S Trailer Service of Helena Ohio
polished and Plasticoated my coach - - I initially hadn't planned on polishing the coach and had a pair of two-year-old steel tanks that were replaced by the new Worthingtons - - had I thought more about my restoration agenda, I could have saved myself nearly the cost of one of the new Worthington tanks. The photo below is of the polished tanks on my Overlander:
Good luck with your decision!
