Tom, nice rig. You are ready for winter snows and summer sand dunes and every out-of-the-way place in between.
Usal. Pismo. Oregon Dunes N.P. Assatigue. Outer Banks. South Padre for a little sand that you can actually camp ON. With a gas V-10 you an also go to Mexico/Baja, which most newer diesel trucks cannot do because of the lower grade diesel that will ruin the pee canister. You have a fine, if thirsty set-up with plenty of power. If you plan on putting less than 200K miles on it, you are good to go.
