First and foremost: NEVER LEAVE ANYTHING ANYWHERE OUT OF YOUR SITE, ESPECIALLY IN THE VAN, UNLESS YOU EXPECT IT TO GET STOLEN OR IT'S INSURED!This will be my first time going on the road for an extended period of time so any suggestions you may have I will take! Still have time to decide what basses to bring and if any of them will be G&Ls
Be very observant of "anyone" watching your load in, that's what thieves will do so that they can see what you have, what you drive, and where you park. Then, at load out, once the gear is in the van, you go with it. Resist the urge to go back in the club and sign autographs for your adoring fans... OR have someone you trust stay with the van and gear while you do, even if you have to pay them.
You can also get cheap insurance for your gear.
I know many pro bands that lost their stuff this way, more than once. Other than that, just use your G&L smarts!
They will cover instruments in your vehicle if you are just transporting them from point A to point B, but if you are transporting them from point A to point B for purposes of making money, i.e. gigging/ touring, then you are not covered by home owners/ renters insurance.
