If you can find a way to clean it before you come home, you will not have to spend so much time to clean up. fresh mud comes off rather easily, and quickly.
I can clean my trucks off, inside and out in less than 30 mins regardless of how much mud I have found.
This takes a decent size pump, and ample supply of water. Volume is the key, and having enough supply to meet the demand makes clean up quick and easy.
On that note, you have found that you are also going to require some larger recovery equipment. Cant get cheap in this area, because as you can see, it will fail. Bigger trucks require larger recovery equipment.
Big truck with big tires, will require big clean up. However the fun is reward is huge. Fun is huge, and it only gets better.
