Hello,
So we have decided to go bigger, This Blazer model sits on your truck rails like a shell, leaving your truck bed open. It was so cool in our old Blazer to just climb into the back without going outside. I added a section in the front for my bigger truck but it can easily be converted back to Blazer style. We have installed a new vinyl from All Terrain Campers with the big windows and rain guard or shade as seen in one picture. In a full almost tornado storm which we experienced in Utah a little water did get in, otherwise dry. It has helper shocks front and rear to help lift the top, two ample solar panels on top, a small rack I used for a surfboard, a counter with small stove on drivers side with a shelf below it and a removable table with two chairs on passenger side, an escape hatch in middle of the bed for star/nature gazing and roof access, a fantastic fan, LED bulbs... other little things. It is very simple and basic, like us. Thanks
