Listen to your passengers. They may notice you getting more tired than you think you are.How many miles/time do you travel comfortably in one day towing your camper? I know there are a lot of variables to this answer but just trying to get an idea planning trips for next year. I am at 75-80% of my towing capacities towing my 212QB with my 2.8 Duramax Canyon including payload.
Fighting head winds pulling a trailer may take more out of you than pulling in good weather. Some days you may wish you pulled over a lot sooner.
