The heated mattresses have a controller like an electric blanket and require 110v AC power.

Get the heated mattress option! We love ours, even though it is a single control for the entire mattress. Ours is even comfortable (to us, anyway) with a thin foam mattress pad.
BTW ours is 8 years old and still works great. We like the heat from underneath better than an electric blanket. And it's great to crawl into a warm bed. One of the best nights sleep ever in the trailer we awoke that morning and it was 53 F in the trailer but the bed was snug and warm!

A heat mattress is great! We don't use one in our RV due to too much power draw when we boondock but we have one at home. The heat rises from underneath you and is trapped by your blanket as opposed to an electric blanket where the heat is only on top and doesn't feel as warm and comfy.
