Bigboomer, not familiar with your model Montana, but on our 3400, I took that board up under the bed to see if there would be more storage room under there. What I discovered was the hydraulic cylinder for the slideout and all the hoses were under that board. So, I simply put the board back in place and forgot about it. There is NO room, at least under our board anyway. Oh, I suppose you could store a few small things in there, but if the hydraulic line ever blew......!
