I've removed and replaced a bunch of Eurovan floors now. This thread will be part information bout the flooring found in these van and partly how to install new stuff.
The first thing you need to know is at the stock flooring is not all the same. The GL/GLS passenger vans have foam and rubber backed carpet. This is very soft to kneel on and great for a passenger van. The vans with the rear bed from Westfalia, the MV and Weekender, hve a thin layer of carpet stuck to a wood subfloor. This is to provide a hard surface for the bed to roll on.
Installing a rear bed into a GL/GLS without changing the flooring makes for a very difficult to operate bed as it just sinks into the soft foam carpet.
It's possible to replace the stock GL/GLS carpet with a wood floor but I'll get into that later.
Not the best picture, but this is MV flooring without its top layer on it in front and GLS pure carpet in back.
The stock carpet in the MV/Weekender seems to soak up and store dirt, mildew, mold, etc. it lets liquids pass right through it into the wood subfloor. When you pull the stock carpet up you may be amazed at what stains are in the subfloor!
The stock wood subfloor is glued into the van and nearly impossible to remove. So it's best to leave it in place and work with it there.
Remove all the seats, seat brackets, bed brackets, and door trim from the rear hatch and slider. The slider door trim just pulls straight up. No need to remove the interior trim pieces. The carpet is just tucked under them.
The carpet is glued down. Sometimes it will just pull up, other times you need to scrape, chisel, pull, and sand it off. Start at the slider door and start pulling. It may come off in chunks.
I go over the floor with a sander to get it totally free of glue and old carpet bits before installing a new floor.
This is a vinyl plank wood look over the wood subfloor. Its much heavier than you might think. It scratches and looks dirty constantly being a dark color. It should also be noted that to do this you need to make a custom carpet trim piece for the doorway. This piece get a lot of traffic and is hard to make last a long time.
I put my flooring through a lot of testing!!
After testing out a bunch of stuff I don't have pictures of I came up with the solution below. This is the stuff I have for sale on the main portion of this site. It's a flexible poly-vinyl flooring. It can be laid down in two large sections just like the stock carpet. Which makes if far more water and gunk proof than the plank or tile floors. It also curves to match the slider entry way and rear door trim. It's durable and looks clean even when its not.
It also matches the existing grey interior color for a factory look.
Different van, Just also happens to ve techno blue.
