camper bed a bit claustrophobic, anyway to get over it

We bought a pop-up TC a number of years ago because I knew I could not handle a hard cover cabover. I tolerated it fairly well, but never really like it. I am a psychologist and I have used many strategies over the years to help me do the things I want to do (e.g., go into caves) but sometimes it just doesn't work. Get a rig that feels right, life it too short to be stressed.
