My 2020 got real consistent mileage about the same as yours with or without the trailer. I traded it in still under warranty because the dealer had it more than I did at times. Plus it was worth more than I paid for it new on trade in. (blown hydro boost oil all over the floor, 3 sets of battery's, cracked charging terminals 2, pin hole in radiator hose, engine oil leak, transmission oil leak I never fixed, and bad rear shocks to name a few. Now the 2022 getting horrible mileage. Larry
