I decided at the onset of the cart build to make it as modular as possible. so I stripped all the canvas to bare chassis... at the time I was driving an Explorer Sport so kept the folding capability, later ran a couple of bolts through the hinge mechanism when I switched to the Tacoma...original step was the length placement of the double ATV gun rack to match the Benelli and AR, I wore my pistol, mag pouches, shotshell trays on a 2" Uncle Mikes duty rig, and over the shoulder single Sam Browne shotgun loop belt for slugs or buckshot in case there were intermixed targets on the stage... I use inexpensive aluminum snap links to attach bags, and trial fit the location with stainless screw clamps and split rings for attachment points...I use heavy duty contractor type tool bags with heavy handle webbing... the weight of the ammunition hanging between the rails and partially supported by the axle...soft sided cooler in the original foot rest platform.. I did not want the cart to wheel stand
my original 3 gun cart has been repurposed to a Steel Challenge cart... the attachment points are now fixed, and are1/4" eye bolts... the snap links are on the bags themselves... GI mechanic's bag, trauma kit, soft sided cooler... I don't carry that much ammo weight any longer.... more creature comfort was added, a Ridgid battery powered contractor fan, attached on a bar between the rails fairly centered, so it can be attached pointing forward or aft, depending on which way the range is facing...to hold a 7' beach umbrella, a PVC tube with a "U" shaped cut to center over the axle and a pair of stainless screw clamps( figure 8) to attach it to the side rail tube.. angled outboard so that direct overhead sunlight fall to the side, not directly on the cart...a 24" folding stool allows me to "roll off" and ease my knee... a loading tray was added to the umbrella support
