A modification I made while in Florida this winter, sorry it took so long to post.
I added a propane tank to the tongue that should not have to be replaced every day like the small cans.
Thanks Auntie M your fix is still there. I will have to shift the tank forward an inch, later.
To make the loops my dad wrapped the tubing around a small propane tank three times. No there is no regulator on the connection, seams my heater will not work with one hooked up, must have a built in regulator for use with the little 1 pound tanks.
The connection at the heater.
And I left provisions for connecting my cook stove to hook over later.
