Hello Melissa Sigler,
Educate them first so their smart. Kidding, haha.
I use a handtruck to carry adjustable equipment in a tub. Get the kind for stairs so it slides up instead of clunking up and down; but, it can scratch stairs. Use long straps to tie it all down and have fun getting that in and out of the vehicle.
There is no perfect solution; I get a workout getting to the clients’ workouts.
