I was very close to buying a new Alaskan 8' Cab over, but ended up going with a Northern Lite 9' 6". The price of the two campers was not far apart, but the NL was more. Our camper's out the door empty weight is 2725 lbs. No air or built in generator. I have a F350 crew cab, long bed.
I really liked the Alaskan, in fact, it was the most comfortable camper I've ever been in. We made two trips to the factory as we went through the decision process. The only thing that influenced us away from the Alaskan was interior room. I think they are well made, sturdy, comfortable and certainly beautiful. Almost yacht like in the interior.
With the Northern Lite on a 5000 mile trip this year, we came in with a trip average of 14 MPG. The truck handled the NL fine, with very little sway. I have added airbags to level the camper side to side as the right side seemed a little heavier. No sway bar on my truck.
Compared to the Grandby that we have just sold, the NL is a moose. It does have a different feel to the drive, but it's no more difficult. I would never take the NL some of the places we took the Grandby, but that is a clearance issue. I'd probably confidently take an Alaskan any place the Grandby would go.
For us, the NL is a mobile cabin, not an expedition rig. The Alaskan would have been a camper that would have gone anywhere I was comfortable taking the truck
