John,
Our ready to camp weight is with empty water tanks. We normally camp where we fill the FWT at the campground when they don't have water at the site and dump the B&G tanks at the campground. We don't have factory solar charging system and now using two 105AH Epoch Lithium Batteries instead of two BB 100AH lithiums. Ollie weighs in around 5100lbs, honestly added a little weight to Ollie since we started towing with a F-350. When we towed with 1/2 ton pickups got creative to keep Ollie's weight under 5000lbs. We have the original 5200lb axles with 12" brakes & Dexter's 5 leaf springs (no 5 leaf failures yet), but I don't like Dexter's wet bronze bushings in the their springs, I like Alcan's spring bushings that are double the wall thickness compared to Dexter's spring bushings.
If we have the wheels refinished, will start another thread about it.
Thanks,
Bill
