I’m sure other people have know about this thing, but I just came across the Kamp-Rite Midget Bushtrekka. Granted, it would seem like you could also just get a trailer and pack your tent on that. Probably simpler, actually… But a trailer camper van for biking? Definitely cool and clearly not just a gimmick given the well-designed (by specs and photos anyway) storage and overall structure of the trailer.
26kg is pretty hefty, but then it’s a solid trailer and has the tent built in. Next thing they’ll come out with a generator accessory and then you’ll be ready to hang with the big RVs!
