Simple solution is to get yourself a tube of the yellow thread sealant for gas, install one long line and switch the regulator to the single tank side, swapping tanks as necessary. When you get ready to pack up, remove and store the long line and reinstall the short pig tail. At least that is how I have been all winter with a 25 gallon tank connected. Just took it off the other day as we are getting ready to leave here next month.
X2, did this through 3 winters using 100 gallon tank. Come summer put short one back on and moved to summer lot on lake.
Kept the other side hooked to 7 gallon bottle just in case there was a problem with the long hose freezing, which never happened even down to -7.
