i just put it in park. never have used the parking brake. ive never had a problem with a tranny. i have over 200,000 miles on this van. had over 350,ooo on other one never had a problem.
I bet those rollers are a sweet thing to have in avan. I went to Harbor Freight and bought a chain that has a standard hook on one end, and a large j-hook at the other.It works perfect, just long enough at 9' to get that front skid out. It cost around $20.00
