Ok my EUC went through to pick up my first M101A2 trailer and I go to get it tomorrow. I have a couple of questions I cannot find answers to. What size are the lug nuts on the tires and how much extra chain do I need for the safety chains? I have lights, zip ties, a 3/8X5" ball lock pin and I will be taking silicon break fluid. I attached my pintle hook to my adapter plate and have 23" of clearance so the trailer should pull level. The tires look good and I am taking a air tank to make sure they are inflated properly before I drive off. Anything else I am missing?
