You know the type I'm talking about. The boxy metal ones with side doors. Not work boxes like a repairman uses, rather more for camping and off-roading. Some of the popular brands are Alu-Cab, GoFastCamper, Smartcap and RLD Designs. I'm in the market for a camper and am probably going with a traditional fiberglass model like Leer or ARE, but these new black boxy metal ones have got me thinking maybe there is a better mousetrap now available. Below is a flyer in case you don't know what I'm talking about. Curious if anyone here can compare one of these tops to ones that have been around for decades.
