The LMC MIP "kit" is basically one big honkin' sheet of vinyl that's sort of molded to a shape vaguely unlike your truck's floor. It is a bit big in all dimensions (which is good -- far better than being too small!) so expect to trim it.
No cutouts are provided for floor shifters, so that the same kit can work for 2WD or 4WD or whatever trucks. You therefore must be careful when you cut it
At least you can just use scissors since it's relatively thin.
I put one in my CUCV 'cuz the original one was worn out. It was a fair approximation of the original, and was affordable and relatively simple to install. As mentioned, heat helps. IIRC I left it out in the spring sun for a day to unroll, and then installed it of an afternoon.
Like any interior work it's manually intensive, so don't expect to just drop it in and roll. You'll have to remove all the trim, shifter boot and console, etc, and of course the seats. Then you wrestle the thing, get it situated just right, and start measuring and trimming and measuring...
Finally, I don't know that the rubber dampens sound at all. It *might* block heat some, but it's 1/8" thick and pretty dense, so it'll transfer heat eventually. (After you put it in the sun you'll know what I mean
)
I'd put down a layer of that reflective bubble-wrap stuff for heat insulation; for noise
and heat you might instead use the thick fibrous carpet underlayment stuff.
