I have a '14 1500 dbl cab with the 6.2 with max tow package. Over mothers day weekend we went camping (towing the same camper as last year) and we noticed that the truck was struggling a bit. We went to the same place we did last year and the same route, same amount of people, etc. My camper grosses around 9600 but we're never near that. When we were rolling, we noticed that the truck was struggling on some "flat roads" and especially up the smallest hill. Last year the truck towed like a dream and we couldn't even notice I was towing anything.

I was wondering if anyone else has experienced something similar?

 

Two things come to mind but you sorta covered one by saying you have done the trip before...
1. Altitude, you can loose up to 25% of your power as you rise into thin air
2. Fuel, if your tank had more alcohol based fuel you will loose some power and if that was coupled with altitude its a double whammy...

Should also consider how clean your air filter is...

 

the air filter is brand new has a replaced the OEM with an K&N prior to the trip. I've been using the same fuel since I bought the truck. I live in CT and went to the same location and route as we did last year with it

 

Ah! that could be your problem right there... if the K&N had too much oil on it , its likely contaminated your MAF sensor.....
Try cleaning the MAF with the proper cleaner and see if that restores the power...
And put the factory filter back in...

 

i'm going camping this weekend, so i'll put the OEM back in, and clean it out, and report monday
