So I'm on vacation and found an excellent deal on craigslist. a used 6505 combo for $450. I am stoked, it came with the manual, footswitch, a proof of purchase receipt, and the brand new tolex look. It even had under 50 hrs of playing

Unfortunately I have a giant van with poor suspension and have a 90lb amp in the back.

What can I do when traveling to help protect the tubes and such inside a 6505 combo?
Just secure the amp so it can't slide around. As long as the amp isn't allowed to slide and bounce you should be alright.
I don't give a shit if you listen to me or not
