Top bunk weight limit?

I'm trying to picture HOW a 500 lb person is going to CLIMB UP into the top bunk? I've witnessed a similarly hefty gentleman walk 30 yards from the customer's driver check in to climb into his truck in order to get into a dock. It took him two minutes to walk 30 yards, then another 3-4 minutes to climb up into the driver's seat. He couldn't bend his knees, had to hang on with both hands and lean waaaaayyyyy over to get a foot up to the next step on the truck. I just can't figure out how he'd manage the athleticism to climb into a top bunk, or for that matter to climb into the back of a van to install load locks or sweep the trailer.

 

1) Dock workers are generally pretty cool about bracing the load if you toss the load locks in the back.
2) Company paid trailer washouts.

(You don't have to be 500 pounds to find a way to... conserve energy)

 

dont forget about parking as close to the truckstop doors as possible, if parking inside was an option they would probably park there too, and sometimes when parking inside isn't an option well they just park inside anyways.

exercise usually isn't a top priority so don't expect them to park on a back row anywhere
