Here's a couple of thoughts.

Do you use the four-wheel drive? Most SUVs really do not use it.

If yes forget about it.

If no, try this. Remove the half-shafts on the front axle. This way the front axles lose all the drag of the front pumpkin and transfer case. Even with the hubs unlocked there is some friction from all that machinery. This is fairly easy to reverse in the late fall when you may really need 4x4.

Also, check your disc brakes for rubbing. The metallic brakes used these days tend to rust. Most of the pucks are cleaned off by brake action but the edges are not swept by the discs so they can rust, which makes them swell up and rub at the edges.
