The steep mountain roads I drive will require that I stay locked up in 1st to 10 mph or less. I wouldn't want to have it come unlocked in the middle of a hair pin turn
I don't know what the grade is in the middle of those turns but some look straight down. Lol
I may have to look for a newer used manual gas truck also. I was thinking of getting lazy and going auto. I've got a manual truck I can take any where, with out the trailer is not bad when in town. Out on the road I'd be pretty beat up after a 100 miles or more. But where I camp I drive very few if any freeway miles. I very rarely drive over a hundred miles. But it's a 2 1/2, 3 hour trip because of the roads
50 grand is a lot of money for a truck that isn't recommended to drive in town.
