I will always remember coming home with my "new to me" GMC 2500. When I backed it up to my Hallmark popup I was convinced that what I was seeing simply couldn't be true. Camper was just too wide to fit the truck. It wasn't too difficult to modify the width of the camper. As I recall, I need to remove almost 4 inches. Hardest part was taking a power saw to the camper! Go slow and think it thru before you fire up the power tools!
I have a number of Black Diamond Apollo's that run on AA cells and recently added a Black Diamond Titan that runs on 4 D cells. I hesitated for YEARS to switch to battery powered lanterns. These have been very sturdy, the batteries last a long time. They are adjustable output and throw a good amount of light on high. I'd recommend these models. I've owned the Apollo's for a year plus and the Titan for 4 months or so. I've used them extensively. For me they are a vast improvement over gas. As always, YMMV.
