Unsure if I can do trucking due to weird body proportions

Now this is going to sound very weird but I just wanted to try to post this here to get some insight.

Basically I would love to pursue trucking as a full time career. I love the idea of driving across the country and like the solidity of the job.
The problem is I have somewhat a hard time with getting comfortable in the driver seat due to how my body is proprtioned. I have weirdly long femurs(thighs) for my height and short torso,arms comparatively.
Being cursed with these proportions, I have to position the seat back so my knees won't touch the front and my arms would maneuver the steering wheel comfortably. Often times when driving a car I have to do the same and have to slouch my shoulders forward which causes shoulder muscle pain sometimes when driving for longer hours.
Now does a truck have more legroom compared to a car, is the steering wheel more forward then a car's?
Sorry for asking these stupid questions but I have never been inside a long haul truck.
This is the only deciding factor for me in pursuing trucking.
