1150 vs. 990

I have never driven 1. a truck with a camper 2. a duely diesel truck and 3. a truck with 4000 lbs in the back end so I have zero frame of reference to make an intellegent decision. Because there are two separate components, you can't go to the Artic Fox dealer and take a camper for a test drive............. :^(

I suspect you will be at or more than 5000 pounds camper loaded and with water. You will likely need some suspension mods to the truck to handle that much weight even with the one ton dually. The real difference between the 1150 and the 990 besides price is the length, the weight is only about 200 or so pounds. If you plan to tow a trailer the 990 would probably work better with a shorter stinger; if you do not plan to tow the inside area of the 1150 provides more living space. Truck campers are small inside when it is raining, windy, cold, buggy, etc. Size really matters.
