I am not going to suggest what truck to buy, but I do wish to address the issue you posted.
Most of the newer trucks are fairly tall now days be it a 1/2 ton or a 1 ton.
I watched these working and seem to do a fine job for an older lady I watched climb in to a Chevy 4X 2500.
IMHO they would be a great addition to any rig and if it makes it easy for the boss so much the better.
Guest I'm cheap ! My new to me F-350 has nice color coordinated!, lighted running boards, with imbeded rubber treads. Soon I went to Home Depot, bought a 8 in step stool with a 300 lb capacity for $10 . It folds to 1 inch thick, and stores in the passenger seat back pocket.
