Can't say I agree - we run skid plates from rail to rail of the frame, then from rail to the outside of the vehicle for sliders. If you're already running both? Why not have a smooth transition all the way across, curving up on both ends the way sliders do anyways. How many rocks do you stuff up in the holes between components? That's the only clearance that would be lost. There would be holes in the plate for access to mounting bolts, and it would likely be as heavy as sliders + the diff skid combined, but it's a pain to move armor under a truck any way you slice it. Prop up one end, lift the other, bolt on, go sledding.
How are you going to mount it?
You can get to the back crossmember easily enough, but what about the front of the belly pan?
Just going to mount it to the back of the front skid?
You can drill through the skid and crossmember, then weld a nut to the top of the crossmember, but what bolts are you going to use? Can’t use a standard bolt, because if you hit it on a rock, it’s FUBAR, and you’re not going to get a socket on it. A counter sunk Allen head might work, but the head is soft; meaning it strips out easily, and a long ass bolt you’ll need isn’t going to be easy to take on and off.
Going to weld tabs off the frame, right next to the fuel lines on the driver side, and the exhaust on the passenger, for mounting points?
A long, flat, piece of steel like that is gonna take a hit in the middle and fold right into the transmission pan or transfer case; unless you use something thicker than 3/16, or add gusseting, which is going to cause the skid to hang lower, thus decreasing ground clearance, and add weight.
My front skid will hold about 1/2-1” of mud on the flat part, increasing its weight significantly. I can only imagine what a belly pan the size you’re speaking of would hold/weigh.
If you’re running a flat belly, where everything is already tucked up above the frame rails, then I can see doing what you’re talking about.
But if you’re still running a stock location transmission/transfer case, it’s not going to work very well, nor is it a very feasible idea.
