I will second Scott's about Bryan. I have sent several emails since buying my old Alaskan, and during the week I don't think he has ever let 24 hours elapse without answering me. If I were to ever buy a new camper I would not hesitate to buy another Alaskan simply based on customer service to owners they will never make a dime from.
To remove the top from my 8ft co, I took it all the way to the top and then ran a 4x4 from side to side under the over cab portion with eyebolts on each end hooked to rafters via a come along. Blocked up the rear and unhooked the 4 cylinders and with a floor jack and an upright 2x4 with a V-notch cut into it jacked up the rear portion and ran another 4x4 from side to side there and then lifted the whole thing a few more inches and drove out from under it. Let it down to a good working height and screwed legs onto the 4x4s. All of my guide tracks slid right out at the top. Getting it back together by myself was another story. That camper is long gone and now I have another 8ft co that is soon to get the same treatment for a major rebuild. Going to turn it into a 12ft nco tray style to mount permanently to a flatbed.
