I recall you have the dry weight and the scale weight listed ...on your blog site? ...I think I remember seeing it...but it may have been your older truck.... I would love a aluminess but freak out on the weight hanging out back there. IT would be great to be able to carry a second spare.
No, I've never weighed my truck. I probably should, but I worry more about handling, especially braking, and I've had no issues there.
When I first added the Aluminess all I had were airbags and the truck seemed to wallow and would porpoise at times, but since the OME lift with heavy springs and an extra leaf it handles about like it did without the camper.
I'm certainly not trying to encourage folks to overload their trucks, just reporting on what works for me. I will say I'm a fairly cautious driver and like to leave space between myself and the vehicle in front, but a few times I've really had to stand on the brakes and have been impressed at the stopping power.
