The OP is not asking what his Tundra can tow... Geez people, give it a break.

Better YOU give it a break. :R This is the time of year when newbies begin popping up everywhere, almost all with same idea - that they can actually safely tow a heavy trailer with their 1/2 ton because, by gosh that's what the truck's so-called "tow rating" says it can! As any of us who have been at this for awhile know that's balderdash ... the OP, or anyone with a 1/2 ton, won't be able to come anywhere near towing a trailer that heavy without exceeding the truck's real world payload capacity - period. Every newbie needs to be reminded of this FACT, regardless of whether they asked or not, the OP included. IF his payload capacity is indeed a mere 1270 lbs and he expects to also carry passengers plus cargo in the truck while towing he'd darn well won't be towing a trailer that weighs 7000 lbs because by definition he would be using up most of that payload rating with trailer tongue weight alone.

As for the OP's original question - water freezes at 32F for everyone, including him, so if he expects to use this new camper "wet" in sub freezing temps the simple answer is he has to provide measures to ensure water anywhere in the system can't freeze. Easy to say, possible to do, but requires specific heating solutions which would include tank heating pads, heated water lines, skirting of the trailer, auxilary heating under the trailer, etc. IMO it's more trouble than it's worth when the simple solution is to simply not use any water during those freezing winter months.
