Stair climbing dolly is a must for anyone in the hobby that is not a spring chicken. It really does make the worst part the easiest. It was down a flight of bilco doors / steps. Setup, still working after the move and “warranty” calls would be more my concern. I delivered a 600 dollar gotlieb gold wings for 50 bucks. Like 20 miles each way. I told him I was no professional and gave him the number of one for repair and maintenance. It did survive a full show. The calls after we’re annoying. The last one he demanded I come fix it. Upon further questioning, he moved it and level was off which fixed it.
