Chet,

Yep, you could get the same results with a D-Ring type rope handle like DeWalt said. And it wouldn't too expensive.

Hope you get something figured out.

 

Ok, so I tried the whole center seatbelt thing and it is a pain in the ***. So in lew of a step, handle above the door or fabricating something Ifiguredthis out. Mabe you have done this already, but here it goes.
Adjust your seat so it is all the way back and laid back as far as it will go.

Find the meaty spot in the seat (part closest to you) wherethe seatmeets the seat back. You can feel the framework or joint of the seatwhere it isfirm. Place your right palm there with the forearm and elbow against the seatback for support

With your left, get a good grip on the A pillar handle. and face as much toward the front of the vehicle as possible.

In one motion pull up with your left and push down with your right and swing yourself up into the seat.A little hop or lunge forward will help. Also, bring up your legs as you do this to help your butt slide into the seat. As you swing in let your backside move past your right arm as if you were trying to reach into your back pocket. As long as you canpull your right thigh high up enough to slide on you should be ok. You will end up gettingina little horizontaly so you might want to flip the center console out of the way in order to have room to reposition.

Unfortunately thisis a lot of stress onthe left arm and upper body. That is why I said a little lunge or hop will help. However, itwould seem to bejust as stressful doing a straight up pull.I performed this procedure quite a few times without using my right leg and minimal pressure on the left. I also had to squat down a bitto make up for your 3" lift that I do not have. I imagine in time when your left leg gets stronger this will get easier. Also, the practice you'll get from now till then will make getting in and out even smoother.

To get out slide your seat all the way back as described earlier. Sit normally in the seat and lay back. Grab the A pillar handle with the right hand. Place your left hand on the door sill just ahead of the jamb. Lean out a bit putting your weight on your left hand. Let your left leg swing out and dangle. Control the motion of your exit with your right arm and your head. Yes your head. Tip your head outward of the truck to get moving. Bring your head up to slow down. When you touch the ground and your weight starts to bear on your left leg you will have more control and will be able to right yourself.

Now you could just swing both legs over and slide right out of the seat, but I find getting out this way hard to control. You're also taking a little "leap of faith"duringthe transition where youdrop from the seat to land on the ground on one bad leg. Of courseI can not perceive yourexact conditionso take all these instructions with abitof caution and have someone there to help you. Hope this helps.

 

You are looking for a high point to grab onto, right? You know those chrome handles that are sometimes put on the exterior of the "B" pillar, perhaps you can mount that to the inside of the truck... but this may require some cuttingof the headliner, and may still not be strong enough. Mastercraft also makes a nylon version of this that is usally hung from the rollcage ofa jeep.You might be able to take your truck to a metal fabricator and they could make you something that would be welded in for strength.
