Thanks everyone for all the input. We really like the Bow buddy but cost is a factor. We may just go with the Enkays.
As I mentioned in the original post, it is my Wife and kids going to Alaska. I will fly up to join them for a couple of weeks but they will be up there the entire summer. Leaving in two weeks and coming back in September. She did it in 2006 in a tent so she knows what she is in for. We are completely aware of the total number of miles going to be put on the vehicle and trailer, I just used 10k rough for up and back.
She is an adventurous soul... wish I was making the trip, too....
