What a find! This would be the Cadillac of H.P. R.V.s.
At 170 lbs without sleeping bag or cooking gear, etcetera, don't think my 50 year old knees would enjoy the trip if it was a long one. Good thing it's a trike, won't fall over at slow speed uphill.
Also at nearly 4' wide, a hazard to itself and others on the backroads. Pick your route carefully to have lots of shoulder.
That said, I once spotted an amazing bike on I-5 south of Eugene, Oregon- it had a BMX front end with canopy, and a camper back end made from coroplast. At least 14' long, the guy pedaling it was going slow but good progress up a slight grade. Didn't get a chance to talk with him, though.
