For full disclosure, I didn't mind the Bilstein shocks that Marlin sells on the street and only replaced them because they would bottom out on the trail. The Ranchos have pretty much the same travel and I have never hit the bottom even with them set on 1. My shocks are in the stock configuration with slightly modified mounts.
Springs make similar looking setups apples and oranges. My rear springs are Alcans that are 5 inches over stock which is about 4 inches shorter than Marlin/All Pro/TG.
The one time that I really loaded it up we had four adults plus enough guns and ammo to form our own seal team and it wallowed down the road. It may have had the Bilsteins on it then, but I don't think the Ranchos would have been significantly different.
The remote reservoir shocks often just supply more oil to help with heat dissipation. Unless you are playing Baja it is unlikely that more volume will make much difference. This isn't true of every reservoir style shock I am sure.
