I don't have any 810 cabs (nor photos), but here are a couple of lists of stuff I've hauled with it:
Eight guitars and basses in hardshell cases
Two triple instrument stands (Quik-Lok GS-430 and Rickenbacker briefcase-style)
Large camera backpack, large tripod, and monopod
Several pieces of luggage
Accessory roadie/photographer
Two basses in HSCs or in a double gigbag
4-space SKB rack
LDS 2126 cabinet
Triple instrument stand (one of the two mentioned above)
Small gig bag for accessories
SKB Pop-up mixer case
Two QSC K10 speakers in bags
Two Ultimate speaker stands
Medium sized backpack with cables/accessories for the PA
Mic stand with boom
Camera gear in medium size bag
Accessory roadie/photographer
In both cases, nothing blocked the windows!
It's also used to haul antique furniture on occasion, such as a Charles Stickley 1599 trestle library table (48"L x 30"W x 29"H).
