I took my Sunline to the family reunion in Milford, PA. Poconos area with winding mountain hills.
Had to stop twice to let the tranny cool as we crossed the Delaware. Idiot light came on and we just took a 1/2 hour break.
This was my first long haul, about 3.5 hours. Have a small cooler in the truck already but will strap a larger one on this week.
My equalizer hitch setup is a joy as no sway present, but I was gripping the steering wheel tight as I climbed the hills. On the ride home I took two breaks and let things cool down, It worked.
But this week I will drop in a bigger cooler, change the filter/fluid and get a temp gauge installed.
All in all we had a great trip, this is fun!
