Thanks for the replies to the OP's issue and wishing you good luck with the project. Here is what I'm looking at doing and maybe some of this can apply to yours. Likewise I have problem with old tank style at the cabin. Based on the helpful info I'll probably install outdoor propane tankless. Removal of old tank frees up valuable space in the bathroom. I can convert the existing exhaust roof vent into a ceiling mounted bathroom fan. Longest run from outside location to kitchen sink, shower and bath sink would be about 15 feet as the kitchen shares the same wall. Unit would go on outside wall next to the water heater. This gives a very short fuel supply line. Winterizing would be a must each fall. Thanks again, Ray
