Great list Eggscape! I think I would also ask about what their black tank regime is...such as, what chemicals and toilet paper they use and if any issues with the black tank sensors? How they dump (ie Do they leave the value open when hooked up?
) ...just to get a better feel of how they took care of of it. Also, good to know if you want to continue using the same products or rinse/clean well and switch products.
If you find a nice used one, I would also call ETI and ask them if there is any recall or such on that particular year or model. I'm not totally sure but I think they can also provide you with the original build sheet options on units they sold. Might need a VIN number??
Best of luck to you on your quest. -Bea
