This is probably a stupid question, but this does not affect the ability to use the second row of seats correct?

It appears the seats are in their normal position in one of the photos, but in the other photos it looks like the platform/base plate of the system extends far enough that it would be under that row of seating.

I’m very interested in your system, the flexibility to choose the drawers and slides that fit a particular use case is great.

Very nice! Wish there was a hybrid version.

Very nice! Wish there was a hybrid version.

Sadly they need someone to give up a vehicle for like week to make them. they had been asking for volunteers and I was considering it until I found out the time frame.

For my two cents literally! I would just pull the two back seats out. Put the supplied latch caps on just to cover it up. Measure off a 3 ply plywood base and felt back it with some contact cement. Done!

go down to the depot get yourself some Milwaukee or HDX plastic containers. Use your tie down hooks in the bed that are supplied already. You're done and you have exceptional storage without the rear seats. You can even just remove the 60% side and cut your base to match that configuration.

And yes it's do it yourself but for my hard-earned money all I'm using it for is a base to put a bunch of stuff on. And I mean stuff like soil topping, fertilizer, bricks, occasional bags of cement, give it a good vacuum throw in my HDX storage containers with my camping gear and my little power station and I'm good to go for a weekend and I can sleep in the back. Oh and a couple of cans of beer spray! Just my two cents

I had some time and had considered going up there (still a days drive) for a few days get a rental to go ride mtn bikes but a week was more than I could do.
