Not sure about getting into a T-bucket, but I can tell you from first-hand experience, getting into a van can be very difficult with certain health conditions. My wife has stage 4 cancer, in 2017 and 2018, she spent over 9 months off and on, in and out of Pittsburgh hospitals fighting to survive. She was in a wheelchair for over a year. The one year at the yearly van inspection, I had only driven it 150 miles during the year. She was not able to get in my Mid-Dodge, the van set for those 2 years, barely being driven. Even these last couple years with her health being much better, I still have to help her in and out of the van. That step up onto the door sill and then the step into the passenger compartment can be difficult when the old body don't move and bend like it used to.
