If the dirt gets wet, your horses WILL slip on it. Honestly, I'm buying mats (replacements in the barn) on sale from my local farm supply stores for $30/4 x 6. My 4-horse slant load needs 5 mats. I use two, 1/4" thick 2 x 6 mats traction mats (that look like the traction on the back of truck bed mats),that I've had since 1986 for the front and back, and three 1/4" thick 4 x 6 mats cattle mats with buttons for traction), for the interior. I also use shavings. My preference is to use the fluffier type bc they produce less dust in transit, and I place those strategically under the back halves of my horses, where the mess is, and they do move some to cover the mats as we drive.
Again, they are removed from the trailer and the wooden floor is clean by the next day after transport. I can always peek in and walk in to gauge my trailer floor.
