Love that! I'd like to do the same. Problem is im more likely to buy an ice castle before a camper trailer!
But the problem with an Ice Castle or any kind of camper trailer is you can't also tow a boat. So you want to drive across country with your camper and do a bunch of fishing on the way? Well I guess it can be kayak fishing. But I want my boat. So a truck bed camper is where it's at! And this one looks nice and light! And on a nice truck.
If I am towing an ice castle its not boat season. My new tow vehicle (tahoe rst 6.2l) goes to callaway 21 September to be upgraded to the 560 package....I could probably tow all three after! Or just tow the boat and sleep in the Tahoe. Plenty of room. Granted I always figured my first cross country fishing expedition would be fly fishing based. Sometimes not using the boat is a blessing.
