Just got back from a great weekend at the family camp in northern Michigan. On the way up we stopped at a Flying J and had the beastie weighed. Fully loaded (two people, full gas, water and propane tanks, tools, groceries for 8, 4 paintball guns and a chainsaw) we weighed out at 11,970 lbs. Weighing was quick and easy and only cost us $10 and they're set up to weigh each axle separately. Ours is 4240 lbs. on the front axle and 7730 lbs. on the rear axle.
Once we had accurate weights I looked at a tire inflation chart and found that I can lower my tire pressure to 60 lbs for a smoother ride. My LT225/75R16's are rated for 80 lbs. inflation but the ride is very harsh at that pressure. Last year I did a quick back-of-the-envelope estimate and figured I could lower the pressure to 70 which improved the ride quite a bit. Dropping it another 10 lbs should make the ride real nice.
We were the first to arrive at the camp and had to whip out the chainsaw to get past a downed tree across the two-track.
Here's our lazy man's camp fire.
One of the nieces tearing it up with her pink .22 rifle.
We also found a few morell mushrooms. Three of us searched far and wide through forest and swamp and finally found this one right next to the trail not 100 feet from camp.
I was able to draft behind 18 wheelers and Winnebagosaurses almost the whole trip and our fuel mileage was a bit over 13 mpg at 60 - 65 mph. I'm real happy about that.
