Last year I wrapped up the HPDE season knowing I wanted to make a changing in my trailer setup. It was getting old renting U-Hauls. Convenient not having to store or maintain it, but the following factors sealed the deal to buy my own:
-Sunk rental cost
-Not always available - having to reserve months in advance
-Lack of storage (tires, tools)
-Having to load everything up the night before or day of the event, and repeat as soon as I got home from a long hot weekend
Step 1: Sell old HF trailer. I had this thing for almost 7 years and beat it to death hauling mowers, firewood, anything and everything. Paid for itself many times over. I refinished it and got full asking price for it.
Step 2: Acquire used Penske hauler.
Slightly different from U-Haul transport:
-6 lug axles
-longer ramps
-slightly lighter (~200 lbs)
-torsion axles rather than leaf sprung
-relocated tongue jack allows tool box mounting
Step 3: Add toolbox from old trailer.
Step 4: Design tire rack
One of the gripes I had was loading/unloading spare tires, tools, etc in the back of my tow rig for every event. The rack allows me to easily transport spare wheels while also serving as storage between events. My toolbox holds most of my "dirty" gear (jack, toolbag, spare fluids, jackstands, etc). I still need to figure out where to put my gas cans - thinking about a small removeable "cage" between the toolbox and front of the deck.
Step 5: Build tire rack out of 1" square .120" wall tube.
Step 6: Engage hover mode on M3 to start track prep
Step 7: Put M3 wheels on rack. I added a removable vertical brace at the front of the rack for some additional support.
Now that the trailer is loaded with tools and wheels, I can test fit the car and play with placement to figure out ideal tongue weights.
