We have rented from both ABC and Great Alaskan Holidays, the rental from ABC was before we had an RV and long story but the DD's and DW wanted to go to Dutch and I wanted to go fishing and then a week in the RV. At that time is was extra for everything except the basic linens and towels and meager kitchen equipment.
A couple of years ago we took the DGKs for three weeks because driving would have taken up all our time. For that trip we went with GAH and could not have been happier. Well stocked with linens and towels and plates and silverware. New 31 foot Winnie Class C. Same thing as noted by someone else, the flights are almost all late night so they left a key for us and the beds were made. Check in and out were easy. Only problem is any left over food has to go in the trash unless someone checking in wants it.
We were interested in going to the ARCTIC Circle and that was permissible and even up to the town above the circle. By the way on the Summer Soltice the sun is visible above the horizon from the BLM campground a mile north of the circle.
I would recommend GAH to anyone they are great. By the by, they do run specials so check them out before you rent.
