I own a 2020 Ascent Limited and am looking to buy a new travel trailer. After an extensive research process (which caused my wife's eyes to roll) I have found the Apex Nano series by Coachman to be the best fit with the Ascent and our desires. The both have the same aerodynamic design but the 213RDS is longer and heavier. We like the layout of the 213RDS better than the 191RDS but the additional 380 lbs is a concern. It drives my expected worst case loaded weight from just under 4200 lbs to just over 4500 lbs. (I'm assuming around 750 lbs of water and cargo worst case for 3 people.) I expect the weight to be slightly less during most of our travels. Does anyone have any experience with towing these or similar trailers that they would like to share? Does my cargo assumption make sense? In the end, I hope to gain insight into what gas milage I should expect with both trailers.
