Hi Larry. Yes the extra LARGE bottom is a real PLUS ! Folding up/closed the metal bottom really takes NO EFFORT at all. It requires 'so little' force that I can literally open/close it with just ONE finger. Though theoretically the SuperLite 'might' be able to transport my entire setup, I still plan to transport the Tyros separately in its own keyboard case (which also includes wheels & handle) and use the SuperLite for taking the EV PA speakers, Ultimate Support Speaker tripod stands & mic & kb stands, and a gig bag which holds the Tyros SubWoofer & satellite speakers, mic, cables, etc.

Donny, admittedly the larger truck you use is preferable for those larger gigs where MORE equipment is needed, but for the smaller gigs, I think the MUCH smaller & much lighter weight SUPERLITE fits the bill.
