XXL Sleeping Bag for Big and Tall Campers

We have an upcoming trip scheduled and I wanted to use a sleeping bag in the RV rental. The bag seem great, is super light and has a ton of room for me to toss around in. Not being a regular camper, I didn't think the more restrictive feet of a "mummy" type bag would be for me. Plus, my "Velcro type" dog will have room to lay on part of it. Can't wait to use it!
