I'll take the 110 degrees+ here in Phoenix over snow and cold any day! As I like to put it, "Short pants, shirt off weather is always good weather!" If Hawaii wasn't so far away from my friends and all, and wasn't so tiny, I could live there again.
I did the same thing with my spares boxes earlier this year. I had four of them of various sizes, mostly fishing tackle boxes, with some very large parts in a "Z-Cardz" game box a friend once gave me. So one morning, I sat down and consolidated the parts into just two tackle boxes; the smaller box being the main one I dip into the most. The deep part of the small box holds two checkbook boxes, one with miscellaneous spare parts, the other with large flat parts. The trays are full of specialized items, such as clear parts, round parts, scrap styrene pieces and so forth.
Unfortunately, my last trip to California, I found out I couldn't get both the spares box and the model to fit in the ice chest, which meant that I had to keep track of three things (ice chest, road toolbox and spares box), so now I'm on the prowl for a tackle box large enough to hold all the spare parts goodies I want to carry on trips, yet small enough to fit inside the ice chest. I'm considering a couple of "double sided" tackle boxes I've seen that would probably do the trick. One of those boxes would probably even hold my "road tools" as well, but there'll be an issue with jars of certain things like putty being upside down.
