Thanks Alan, I have actually a few reasons to do it, getting older, more uncomfortable on the ground, I tour in Autumn and winter mostly, so it is colder in the tent all the time. The dog's comfort also, as he is a part of me, he is my shadow, so the best I can do for him, is what I will try. The wet weather aspect. Lighting all around me in the tent. The crazy wild dogs. and other things. I do know the negatives, but will give this a serious workout, and if it fails , I will tell you guys why.
