New '22 Chev Colorado 3.6L V6, 8sp-tran, 2wh drive with factory towing pk & brake controller = after 8500+ miles so far = 'GOOD'.... EPA MPG rated for 18city/25hy/21combined average - so far all MPG's have been right on the numbers++. First tow trip to N. Calif. in Sept.= 1765 miles/93.7gal = 18.84mpg (part of this trip included a good "up-hill climb" around the back side of Mt. Rainier). The PU has a max trailer tow weight rating of 7000lbs which I should be good on being my teardrop right now weighs in at 1900 total lbs. maxed out. (axle weight=1720lbs-toungue=180lbs.) which leaves me 'room' for some more add-on future lb. space if need be.....

Update - 2023/24 overall towing 'gas mileage' ? = a total of 5510 miles of towing ='s using 293.8 gals = 18.75mpg overall. One trip from here -W.Wash. to Kalispell, Mt.& back - included a total of going over 10/11 mountain 'E/W' (Cascade&Rockys) passes. Was also able to get one long steady 'freeway' run in getting a average of 19.3 mpg for almost 500miles (GrantsPass Ore/Stanwood Wa) heading home from Calif. on the last towing trip ... The PU so far? = I'm good..... with just over 20thou on it now & no problems to speak of, yet...........= it's been fine
