You will be fine, sir. I took my V6 SR5 to upstate NY and back -- and then to Michigan and back last year. I have been back and forth to PA twice since then, and will be driving to Michigan & back at the end of this month.
My 4Runner is bone-stock, I use Mobil-1 5w30 synthetic and it does just fine. Keep your tires rotated (front to rear) every 6000 miles, be sure that your air pressure is at the proper level (spare tire too!) and keep an eye on your fluids. Change your oil and filter before you leave, so that will be one less thing you need to concern yourself with during the journey. Any good synthetic oil will be "heavy duty" enough, especially one like Amsoil, Mobil-1 or Castrol Syntec.
I have the stock Bridgestone Dueler H/T tires and now have 13,000 miles on my truck......and they still look brand new. Unless you are going 500 miles on the Rubicon Trail, I would not expect trouble. Even at 75 to 80 mph on the Interstate, the 4Runner's tires hardly heat up at all.
Good luck and be safe!!
P.S. I never drove a personal vehicle with a trailer, but have driven a Mack semi with a 48-foot trailer behind it.

I am a truck driver by trade, but usually just drive a large straight truck. I only take the tractor-trailer as a "fill in" when the boss needs me.
