I made one using a mono camera Pole that adjusts and locks to different heights. It also swivels 360 for either camping flood light or task/cooking lighting for working on the tailgate. Drilled some holes and attached with u-bolts and rubber to eliminate rattling.
Those that have the Variant model. What bedding are you using? Will it fit those dbl square sleeping bags with pillows even when packed up? Planning also to put a thermal camping mat underneath.
