I'm the one, shoot me a PM when you get back. I've got a few ideas but first want to dissect it and see how easy the charging points go back together. I'll probably take it apart in a bag in case anything is spring loaded. Once I see it apart ill decide which direction to go with it. Some options are to gut it and use it to store extra tanks, batt, attys...another is a smaller battery and room for tanks...another is to replace battery...last is to transfer guts to an old school wooden one-hitter or dugout. If you don't know what I'm referring to that's about all I can say openly on the subject 8D
Dugout is a good idea.
I have also thought of making a custom wood pcc using the contacts for from the eRoll pcc. Make it big enough to hold some extra carts.
At first I thought make it big enough for an extra battery, but find that is not necessary.
