I have gotten 18-20 highway and 17-18 around town. Strangely enough, I've gotten better mileage at 3000-5000 feet in Eastern Oregon then at sea level. Keep the cooling components in top shape and it will be reliable. I was advised to change the oil and filter religiously - which I have done every 2500 miles.

A proper bull bar is designed to put you up and over a kangaroo (kangaroos get very big). The one I have on my Raider is for sagebrush and lights..., if I decide I'll use it at night enough to warrant the expense.

The jury is out, as far as I'm concerned, on snorkels. Here in Australia, they are ubiquitous. I don't plan to ford any rivers, but in the outback here they are necessary. I have never seen any proof that they positively affect performance.
