Tahoe vs Yukon Denali

[Black_Eagle]

We have a 23 ft Jayco Jayfeather dry weight #4100. Current TV is our Honda Pilot touring which lags a little on steep hills but transmission stays nice and cool.
Looking for a larger SUV for and am comparing Chevy Tahoe vs Yukon Denali. I've got a family of 5 plus large dog and not sure if the 5.3L Tahoe can handle the Rockies or if I need the larger 6.2L in the Denali. I don't expect to be getting a larger trailer in future but you know how that goes. Need SUV for family seating arrangement, trucks are out.

Thanks

Tahoe will do just fine in the Rockies wth that TT but for a family of your size, I'd get the extra 18 inches in the Suburban or XL.
