Thanks for the comments and feedback guys! Love getting input on the build.
Articbus, good to hear you've got foam in your van and it does well. I'm guying to be using foam to fill the cracks and gaps for more insulation. What part of Alaska are you in? I'm building out of and living out of Anchorage right now.
CherryBomb, I actually just ordered a custom mattress from them yesterday! Getting it built to just an inch larger than the dimensions of the bed (I reason overlap on the wall is better than an annoying crack,) and four inches thick. I'll be curious to see how it works in there. I have no doubt it will be comfortable enough, I'm just hoping its not too firm to make opening the under bed storage a pain. I do like your idea of using a crash pad as a mattress, but, I'm thinking it might not have enough support to sleep on comfortably?? I'm not a big boulder though, so I have little experience with them. It would be slick though for those extra scary routes. Just pull out your mattress and use it as some extra pro!! That's a hell of a score, an 06' with only 50,000 miles, congrats!!! Looking forward to seeing your build, point me in the direction of your thread once you start it.
Ordered a bunch of goodies over the last week, gonna have a lot do with em all once I get back into town. Got a new stereo coming in, ordered the propane heater and the roof fan/vent, and my battery/inverter/doitall for the solar setup. Went with a Maxxair Maxfan. I love the fact it works in the rain, and it looks like a pretty pimpin unit! For a heater I got a MrHeater Big Buddy. Love the fact I can run it off of both 1lb bottles and up to 40 lb bottles! And then I ordered a GoalZero Yeti 400. I'm not gonna do solar this winter, I'll wait till next summer for that, but this unit allows lots of expansion, while also being able to hook straight up into the van battery. Should make for a slick setup.
All in all, I'm feeling pretty excited to get home and get my hands on all these goodies!
