We're pondering the same question even tho our trip is only bout 7-8 hours.
DW & I are fixin to leave next week and head down to Mesa to visit with DS for a few days. Debating whether to dewinterize before we leave. Nights are still getting down in the lower 20's & will still be in the mid to upper 20's next week. Think I'll do what DJ does and fully de-winterize and then sanitize the system & then blow all the lines and wait till we get there to put any water in the tank. We always carry a couple of gallon milk jugs with water to use in the toilet.
