If your truck has a 9900 gvwr and let's say, dry, you have 3700 on the front axle, you probably want a tire that's rated for at least (9900-3700/2) 3100. That would be the max load you could put on the rear axle anyway according to the gvwr. If you have more of the weight on the front, you could run tire with a little less rating.
If you could weigh the truck wet without the trailer and atv's, you might have 4500 on the front leaving you 5400 of capacity for the rear axle and then you could get a tire rated for 2700 lbs.

Load Range Rating Really doesn't mean a whole lot in todays tires.
For example: A 265/75R16 D in most cases has the same weight limits as a 235/85R16 E, even though they are same height (the 235 is narrower).
Now if you could find a 265/75R16 E (there are a few out there) it would feel much stiffer and can carry more load than a 235/85R16 E for the simple fact that its weight limit is much higher.
The more working air volume often means less psi's and vice versa.
The point is that you need to consider much more than just load range, the tires working weight limit is a much better measuring factor.

Tire actual weight rating is definately a critical issue... Just as is proper rim width. Following manufacturers recommended rim width is important-
IMO If you want to run a bigger tire: Also get a wider rim.
