We have one of those that we use to carry p.a. gear. It’s great for what we use it for!
On the very rare occasion that I still need an amp, I just stack my gear on top of my cab that has casters, throw a gig bag over my back and roll it down the sidewalk. Job done…end of story.
No pavement? I’m going ampless, period.
The RnR cart is perfect for a weekly gig where about 50% of the 100-yard loadin is paved in uneven bricks.
Another room we played monthly had a 50 yard stretch of loose gravel where I pulled a collapsible 2-wheeler with much larger wheels. Took a couple loads, but no biggie.
Ampless isn't really an option in our world. Most venues we play that provide FOH support have small 12" 2-way mains and sometimes-smaller monitors. The couple that have more substantial, pro-level sound have absentee or often incompetent sound techs. When we provide PA, it's strictly vocals/kick to keep it simple.
