Dry bulk or flatbed

Maverick USA told me I'd never pass a physical, but I have a dot medical card and a cdl.
I have a "bad" left leg.
Over a year ago I was shot in the leg while hunting. It left me with permanent nerve damage causing foot drop. I wear a brace and you'd never tell unless you looked hard at how I step. I just cant pick my left foot up, can push down with full force and can still balance.
I tried to get my cdl with Maverick USA but they stopped returning my calls when I asked about their company physical. I'm now with a mega pulling van but would like to pursue my original ideas of flatbeding or equipment haul after I get say another 10 months of experience.
If that isn't viable could I pull a dry bulk tanker with my condition? My dot physical has no restrictions or limits. I was a log cutter for a while even after my injury. If I can tromp through the woods and climb on trees with a saw I can climb up on a trailer.
