1994 Toyota 4Runner maintenence

I have a newly bought 1994 4runner and I was planing on traveling from Washington to Arkansas in. I am a new mechanic in the Army and I was wondering if there are certain services I need to do before I take it on a long road trip. The timing belt was changed at 95000. I love to go out in the mud and I do wash off the engine after.Thanks[img:f8d104a5a7]http://www.2carpros.com/forum/automotive_pictures/173440_Shontayas_visit_013_1.jpg[/img:f8d104a5a7]
