Man, I know it sucks loosing power assist, but you guys these days are a bunch of creame puffs ! Assist is just that, you need to learn to handle the rig without it.
I cut my teeth on a 2.5 ton with no power assist ( and I do mean literally, was working in a warehouse at 16 and the boss comes in and says, " you just got yer license right... uh hu.. OK, you're the new truck driver, everyone else around here has too many DUIs
Went from that to semis with no power steering ( try backing one of those suckers with a heavy loaded trailer into a dock
Now maybe it's just because us old farts have a certain amount or orneryness left in us from a lot of hard living that that overcomes totally useless bodies, but I'm half crippled , can't barely stand up these days but I can still handle my truck in a stall out.
I STRONGLY recommend for those unaccustomed to handling heavy unassisted rigs, to find a dirt road, preferably curvy with nothing to hit on the sides, and making sure you can kill the engine without locking the steering, and make some practice runs ( if it's got ditches, have a friend follow with a chain) but learn what it takes to handle that thing like a man You will feel like you are stuffing yer foot through the floor and your back is going to tear the seat off the floor, but it WILL stop, you have the same brakes you've always had, you just dont have the pansy pan up behind the master cylinder doing all the pushing for you. Same with the steering 10 and 2 aint gonna do it, but it WILL turn. After a few trys you'll be an old pro and then you wont panic if you get in a bind out on the road
