Nothing bad about your stuff, Vintage, it's not a contest, or I'd be last place...
Too bad the dually was left to suffer all that mouse damage. Washing bird crap off is no big deal but getting rid of mouse piss smell is. I've used a mild solution of white vinegar to knock it down in the past. Good move on the trailer tires. I always run E's on my car trailer too and D's on my single axle camper. The only thing I have different is my winch is an 8k to not work a smaller one so hard pulling a dead pickup up the ramps. You can double up the cable with a snatch block and effectively double the pulling power, if you ever need to load a heavy vehicle too.
