Remove your lunette. The large nut on the end of the lunette is a castle nut and SHOULD have a cotter pin.
X Delta Box & Coleman Battery Charger Install:
I ordered a Delta Pro Box from Delta Industries for the front 'A' frame of the trailer. I will keep a deep cycle battery in there along with other items. I got the unit from Delta on e bay and saved about $60 bucks. The Delta box is polished alum treadplate, 33 inches wide at the back and comes to almost the top edge of the trailer. click here for Delta Box
In addition I picked up a Coleman CL 300 solar battery trickle charger, 1.5 Amp/Hr that I mounted on top of the Delta box. This will keep my battery charged durning times that it sets up between travels.
Install:
1) Set the Delta box on the M101 'A' frame where you choose and then center it. The M101 has grab handles that are mounted to each side on the front of the tub and connected to the A frame. I used the bolts that held the front of the grab handles on as mounting bolts. The bolts screw into fixed nuts on the inside of the A frame. Center to center is 15 3/8th inches on my trailer, yours might be different.
You will need to use a spacer in the front of the Delta box in order to level it with the grab handle supports and to lift it off the shock spring that is on the back of the lunette.
2) The Coleman battery trickle charger is simple as it already has the mounting screw holes in the plastic frame, but the unit does not come with screws. I used a 4 stainless steel screws to mount it on top of the Delta box.
Time: About 1 hr to install the Delta box and the Coleman battery charger.
