Refrigerators
[Gary B] Hi Tony, 2 way refers cost less, are less compilcated, then 3 way refers, and many folks feel it is perfectly safe to use LP. The 12 VDC operation draws a lot of amps from the electrical system (typically 15 amps) if your tow vehicle is not equipped with a heavy duty alternator, it may not be able to keep up. If you stop for a while to do some sight seeing, etc. and forget to switch to LP it will drain the battery very quickly. Happy Trails GB
