If you are laying them down... paint tray..
If near a salvage yard or large city, look for or run an ad for single saddlebags.. like Shoei.. that would be cool..
The coolest cabinet I have is a lockable 6 ft high white Pharmacy cabinet.. my only regret, i did not grab all 3.. was high bidder..
.. very well made compared to the Echlin ones I have...
