Added a slide tray to basement of 3250BH. I made a much smaller one for my previous TT. The design allows long storage to the rear of the right compartment. I also made the second level removable or I can flip it up when out to get to something. I will live with it a while and see if I need to make any changes. I can also store things less than 2" tall under the tray as well. Did not show that. I will say it is a bit heavy, but I wanted more tongue weight anyway. It could easily be made to be less heavy, but I used materials I had on hand as well. All in for about $100 counting the materials I had on hand.
