I'll post some pics shortly. I got detoured with installing my solar system which I will post a write up as well. It's been quite an adventure. The Hallmark Utes definitely need some reinforcing due to the nature of the cantilever effect of the Lagun mount. I found that I could push down on the front edge and make the table move up and down quite a bit. What is happening is it's flexing the sidewall under the dinette that the pedastal is mounted to I went in and reinforced the inside with 3/4" plywood and added 1/2" plywood the the entire outside. I'm still not finished and I'm debating weather to shorten the mount so that all four bolts go through the side wall. I saw where at least one of the install jobs in the 4 wheel campers they shortened the mount. I did cut the vertical leg down by 2" but it still needs a couple more. Here's my first attempt at downloading a couple of pics. I had more in my Iphone but they were blank or all red so I'll retake and put in a full write up.
The first pic is where I filled in with 3/4" and where the tablemount will be installed. The second pic is where I reinforced the outside with 1/2" plywood. It makes putting it in the back of the truck a little tighter but it still fits.
