Air Streams way over price and not worth If you have a pick up get a travel trailer and explore. Ive done the truck and camper and liked it because I could tow my boat, but they are cramped and kind of dangerous with there steep steps. We are just 70, and enjoy pulling our 29' trailer around and exploring. Wedo both dry camping and State Parks with full hook ups. It's also nice having a vehicle do scout around once you've un hooked your trailer. They make really light weight too.
For the cost of one trip and rental of an RV with all the fees you could buy a used Toyota Sunrader with better gas mileage and still have shower and toilet. Much more stable crossing the Rockies than pulling a trailer in my view..last time I came back from Bend there was a truck pulling a trailer that flipped on the mountain pass in a very bad spot...those trailers can fishtail
When I was 17 - a year after getting my driver's license - I went to England with my dad and brother. Dad rented an RV and tossed me the keys. I drove us around the country for a week, on the left side of the road mind you. How I didn't kill us is still a mystery. But it was a blast.
If you have a weight distributions and sway bars set up, they are very manageable. Ive towed mine down the Columbia Gorge in big winds and it did fine just go a bit slower.
To me it's a lot of ballast to haul around and parking it is seriously limited....I prefer the class C rigs like the Toyota or a Minnie Winnie....glad you have a stable rig....semi trucks haul big trailers...just not how I'd like to travel
