First road trip
 

I have been reading this forum for about a year now and it is a great source of information. Going to be taking my truck on a 1600 miles road trip. The last 800 miles of the trip i will be towing a uhaul type trailer with furniture weighing about 1200lbs. The truck is all original a 94 with a 4.3 liter vortec engine. The truck has the towing factory package and about 160k miles. Any suggestions on what to replace before the trip to help avoid a highway breakdown. Thank you for having such a cool forum!!
