Do what you want with your own truck, but just in case you aren't aware...there is an aftermath, after mud. Mud will quickly destroy things like u-joints and bushings and brake pads/rotors. It may be fun, but that gritty water will seep in to many things. You might not be happy later on when you have a problems with a $40,000 truck. That's why most people buy a $1000 beater and take it in the mud.
I routinely take my Jeep trail riding and avoid mud like it is the plague. It isn't worth 4 hours of cleaning for 5 minutes of play. Plus you never really get it all out of there.

I did a little offending during a big rain storm. I just found some flooded roads and cleaned the underside at 40mph. :-)

Try a silicon spray lube or a moly lube that drys on the spring pads to make the squeak go away.

Best trick I've found so far is to just hose the clumps of mud down real good and then wait a few minutes and let the water soak in to the mud. Then repeat as necessary until the clumps just fall right off with no high pressure or scrub brush necessary. Just park it in the yard, hose it down and then go find something else to do for a few minutes until it's time to do it again. Once it's completely free of the clumps, then you can get the soap and rag out.

About an hour in the mud, and two days of cleaning later I finally have cleaned almost all the mud off.

I think that will probably be my last time mudding, well at least in my truck lol.

Some of us "mud" as a course of our daily jobs. As an exploration geologist in springtime Nevada, mud is an everyday "joy" this time of year. I agree that it is best to soak the mud initially, let it sit for a few minutes, then pressure wash it off. Mud will get EVERYWHERE and needs to be cleaned off. Mud by definition is clay-based. Clay takes time to absorb water. So in washing off mud, let the water have time to absorb into the clay-based mud. Trust me, I know...

Puddles are great for cleaning the under carriage. But the pressure sprayer is our best friend. Mud on!
