I missed the fourth jack in the frontal pic... I have seen a lot of campers with only three. It just doesn't make sense to me. Lifted half ton hey? Not too clever. I was worried about the extra couple of inches from the shackle reversal I am going to put on my F350, but I talked to Sky from Sky Offroad in Oregon (where I get the reversal kit, we have the exact same truck), and he runs a taller 4" reversal with a 5800 lb 12' camper! Now that's a biiiig camper! Mine should be around 3-3200 lbs loaded. I guess I should get my wifi fixed so I can post a couple of pics of the new combo... The Winni looks right at home on the dually!
