John....the Alaskan isn't an off-the-shelf item per se, it can be ordered in many configurations. While you may be a year away from ordering one, it will still take time to build it. They will ask you how you want this or that, what layout you prefer, if you want power to the roof vents for a possible powered fan at some point in time, etc.
Where the batteries will go may be dependent on which side of the engine bay the hookups for your camper batteries are located, all kinds of stuff. So, with that in mind, you first need to haunt Craigslist every week, I suggest you check Seattle and Portland on alternating searches, search San Francisco and search Los Angeles. CL is funny about the searches. I look for "Alaskan Camper" then "Alaskan Cabover" then I look for combinations in the search pattern of 1) with pic 2) in the title and 3) I check ALL the near boxes and then I check none. This takes time, but you would be surprised what you find listed in one search pattern that does not show up in another!
As you go through them, create your data base for each year, starting from 2018, 2017 and back a couple years. It is possible to find an immaculate camper that has been stored indoors and not really used/abused that way.
There just aren't many off the West Coast it seems or even in Canada.
Each sub-file is for another set of pics posted by a seller with an eye to getting the LAYOUT you want. Beyond that, monitoring the WTW for the intricacies of solar power and batteries, 'fridge options, ovens, toilets, etc. goes on and on.
By the time you are ready to purchase yours, you will actually have seen what works and heard from those who are ordering them what features are must-haves or no-so-needed.
Just remember, if you go for a 10 Ft. CO or even an 8 Ft. CO (or the NCO) you should be driving at least an F-250 or a GM version of the 3/4 ton trucks. You have to decide if you want a 4-door or one with a smaller jump seat extended cab as the turning radius is huge for the 155" WB trucks (an 8' truck tub is a necessity).
"Knowledge is Power"....and it saves you money to learn from the guys/gals here on the WTW!
