Scale, you're just like me. I gave up the double level rolling "do anything anywhere" boat anchor for two smaller ones, 3 if you count the gas can for my gassers. One for glow and gas (a field box with a few drawers for tools), a tackle box for my electrics, and the trusty red plastic gas can. For a while I tried the roller,but found out quickly whatever you put in it, what you really need is at home on the bench. If I can't fix it, I don't fly it, so I usually take 3 planes to the field and fly what can. I have a workshop at home for a reason.
