Hey Ernie, View my profile and earlier posts you will see That I have safely traveled thousands of miles with my 2006 Dodge 2500 SRW CTD quad cab 4x4 long bed with upgrades with my 1998 Lance 990 11' 3" dry bath model with a dry weight of 3250lbs. and a wet weight of 4000 lbs. The rear axle on my truck is rated at 10,400 to 10,800 lbs. from what I have researched. Traveled over 4000 miles with stock 17 x 8 forged aluminum wheels and Nitto 285s high load index tires from Dallas to Florida up to upstate new York and back to Texas before upgrading to 19.5 wheels and tires.
