Dryer vent advice

[codeman671]

We just had electric and plumbing done in our new/old camp to set up a washer and dryer. The dryer is not on an outside wall. Need to set up venting.
Best choice is to go down through the floor, but I don’t think I want it just dumping directly under the camp. Having all that moisture and heat dumping under the house can’t be good for it. Probably going to have to run it out to the side of the house. What have others done? It has to be pest proof of course.
