When we go camping, we never go over 65-70. We can't forget we are towing a barn behind us and things can happen that may be worse at higher speeds. I prefer to leisurely get there. I'm retired. I don't have to be home by certain hour.My Hemi gets low 8's towing our 5k TT up and down the I-5 corridor at 70-75MPH. Just let her eat.
