Bill....in a nutshell. Every time I wheel my equipment in with my R&R cart, I think to myself that, with the enormous amount of equipment we have to use nowadays, I'd be lost without the "cart." I count my blessings and say a silent prayer for whoever invented it! Before this I used a large dolly. Never again will I go anywhere (not even the supermarket) without the R&R cart.

If you're doing multiple locations on a job, I've even set my amp on the "bottom" and used props on each side to hold an open keyboard at a height ready to play. All you need to do is "unplug" and go to the next location. I've pushed as much as 200-300 lbs with one finger (on a smooth, level floor)...no strain and no pain. Always keep the wheels lubricated and it almost moves itself.

You can open and fold it literally in under a minute.

You can cross grass and rough ground with the standard wheels. You can even go skateboarding with it (only kidding).

One suggestion. I'm not sure how the new ones are, but my design (about 4 years old) has one of the side "guard rails" hanging loose when you transport it folded. Simple remedy: get a bungee cord and stretch it from the top to the bottom to hold it in place.

You appear to be doing a lot of this type of work. Buy one and you'll wonder how you ever got along without it!
