Tow vehicle and trailer check list

So we just got back from a horse event that was 10 hours away. Everything went smoothly but it got me thinking. What does everyone else do before hauling long distance?

In my case I'm using an 11 year old F350 that sits for the vast majority of its life. It has just over 110k on it. Before leaving I changed the oil, checked brakes, bearings, fluids, U-joints etc. At what point should I just start changing things like hoses? Same for the trailer. Other than repacking the bearings and checking the brakes what else should I be doing?

At that mileage /age I wouldn't be changing the hoses unless they start to feel spongy. Hell, I've got 243k on my 21 year old tow vehicle and I wouldn't plan on changing hoses unless they start to feel soft or are visibly leaking.

I do most of what you're doing. Plus I usually carry a spare belt and tools and stuff. Oh, and check tire pressure, but I'm sure you're doing that too. I might think about a transmission service if you haven't done that in a while and it's an auto. Maybe change the fuel filter? BTW, are we talking gas engine or diesel?

I don't travel with my wife on her horsey stuff, and she doesn't go with me to racetracks, soI try to make sure my wife has and keeps loaded all the necessary tools to change a tire on the trailer.  Not that a lug wrench and a Trailer Aid (which is awesome for a tandem axle trailer) take up that much room, but sometimes they get parked elsewhere.

Once checklist item I should have used on an occasion in the past is to make sure the hitch is latched before I load the lawn tractor onto the trailer.
