On average ,how many miles do you drive a day? I am planning an extended trip next summer and plan on 500 to 550 on a few days. Those sections will be Interstate or limited access toll road for the most part. I drive a 2014 F150 Screw and will be pulling a 27 ft trailer ,yes I have weight distribution and sway control so that should make an easier tow. I have towed a max of around 800 mi before on a family emergency towing a 14 ft enclosed trailer ,I never want to do that again. So am I being too ambitious on my long days?
