There are different types of van liners based on what your purpose is. It could be for moisture and preventing rust, insulation from heat/cold, liners for scratches and dents, etc.
Could you tell us what your specific project is?
I would check with a van-customizing shop for their recommendation.
If you are looking to insulate them this would work: We recommend using ¾” to 1” polyiso or XPS foam board to insulate your van, glued in place with either Great Stuff spray foam or 3M High Strength 90 spray adhesive. If you choose to insulate your floor, we recommend using ½” XPS due to its compressive strength.

Hi Gail, it will really depend on what you are trying to protect them from (also what type of van it is). Can you provide some more details and we would be happy to help. Thanks!
You could use moving blankets and put up with velcro.
Gail: you could always hang old quilts or moving blanket with heavy duty velcro.
Peel and stick carpet tiles could work.
You could use Polystyrene, or Roll of Aluminium backed padded Polystyrene, or bubble wrap or old Carpet stuck on.
The trendy solution is very thin pieces of wood flooring applied.... https://www.youtube.com/watch?v=PfjmpjjuX9k
