Yes, there is backing in the place you would bolt the mount. I drilled it out and used 1/4" bolts to mount it. I pulled it about 500 miles round trip last week and it seems to have held up really well.
The only thing that did come loose was the bank of drawers above the fuse box. I have plans to completely overhaul that!
And then my next mod is going to be to rid myself of the worthless mattress!!
