The only thing missing is the large doggie door. That way, my large attack dog can jump out and scare the pranksters off before they tip you over while you're camping.
Go electric! That camper has a ton of square footage to hang very large solar panels. Personally, I'd want a 6.5hp engine. Motorists are gonna expect you to be moving faster than pedal speed, maybe 20mph.
I can only imagine the crosswinds. This must be in Asia, maybe China many years ago. No need to worry about heavy traffic back then.
That'd be a homeless person's castle, no offense meant.
