You might want to look at some of the highwall pups that are out there. Nice features with hardwall bathroom which is a must for DW in the middle of the night. I agree with bondebond, nothing beats sleeping under canvas with the screens open on a nice cool summer evening. Like you we tented for 16 years before moving to a pup and I love it. I just wish I could use it more.
BTW, the help I've found on here has been invaluable to me.
