For the OP, looking at your build thread and 'wheeling area, you may want to look for a
rear shock with a remote reservoir. It would provide for added cooling if you are driving at higher speeds off-road with that much load. Radflo is the only manufacture with a remote reservoir 2.0.
I went through this just last month and ultimately chose the Fox 2.0 in the 3-4" variety (985-24-076, 985-24-087) from Advanced cycle parts on Amazon for just
$116 each. They are just a hair shorter than the OME "L" shocks I was replacing. I was content with the OME shocks and the price of the Fox shocks were nearly identical. If the OME twin tube shock can handle what I do, there is no reason the Fox monotubes should not be more than adequate. Details of my truck can be found in the link in my signature line.
There is a lot of cross talk about how a heavy truck will blow out Fox shocks...just not true. Sure, the shock will work harder (heat and break down the oil) if the valving is not matched well to the springs/weight but it will not contribute to premature "blowout" failure. Failure will be due to driving the truck
beyond the limits of the shock. The better approach is to ensure you have the proper springs for your load and driving intentions, then proceed to shocks. Over-landing, high speed dirt, or any such mix will require a shock with additional oil volume to remain cool.
I would agree the Fox 2.0 may have valving for "lighter" setups, but these can always be re-valved in the future. There are numerous local shops that can re-build and or re-valve these 2.0 cheaper than what Fox charges. The only way to make the 2.0 better would be the option for a remote reservoir, however the price of such an addition nears the price of 2.5s. I feel many manufactures have dropped that option and simply want consumers to buy the 2.5 or 2.5 with reservoirs (spend more $$$). If retailers can sell the Fox 2.0 for less than $120, than I see no reason why Fox could not produce a 2.0 with reservoir for less than $200 (which I would be a buyer at).
Last but most important,
PUT A BOOT ON THE SHOCKS. Not even $15 for a set:
