VEVOR Dog Stair for Cars, Wide 4-step Dog Car Steps, Folding Dog Car Ramp with Nonslip Surface, Portable Pet Steps Lightweight Aluminum for Car, SUV and Truck, Supports up to 250 lbs

This is the BEST purchase ever! I have 2 large German Shepherds. I drive a lincoln navigator and this is perfect!

I 110% recommend this product. I'm sure it will work fine for your van side doors. As long as you have the space in your garage. Mine use the hatch, so the garage space isn't an issue. Seeing how you will be using it for a side entrance I would measure the length of the stairs as well as measure your garage space. If you are using it outdoors, then no problem at all! see less This is the BEST purchase ever! I have 2 large German Shepherds. I drive a lincoln navigator and this is perfect!
