The new 1172 truck campers have portable 30 lb tanks? Wow, that’s kool. I could boondock a lot longer with those.
I only have 20 lb tanks on mine so don’t know about obtaining 2 port types; never had the need so never looked for any.
Being portable tanks,,, I think it’s required to remove them for filling but I’m not certain. I moved the regulator to the back of the propane compartment on our 1062. I can slide the tanks in-and-out with MUCH less hassle.
Good luck with your search.
