Just to reiterate the point of being self-sufficient, today I discovered that I drove to Florida on half my trailer brakes. Seems the dealership that installed my 45* axle (to replace my sagged out suspension) used household twist connects to reattach the wires they had to cut... and shockingly enough one failed. And they didn't even bother to waterproof anything. They had to do the work so I could get the free replacement axle from Dexter, but I hate letting people touch my stuff. Thankfully I brought my electrical bag (I always do) and have made temporary repairs. When I get home I'll be redoing it again proper-like (plus replacing all the sensor wires for the tanks which are factory but look sketchy as heck).
