In the sticky Truck camper university , on the second page , scroll down to TOWING/HITCH EXTENSIONS . THERE are several good threads explaining weight distribution with hitch weight and it's effect on axles , including simple ways to calculate .
Cool thanks, so like I said, not 300lbs
170" wheelbase length
60" hitch to axle distance
500 lb tongue weight
60 / 170 x 500 = 176
Yes, you understand that part. What you're not getting is the rear axle will see an additional 5' x 500lbs in your example, so 2500 ft lbs of torsional force or moment (less because the rear spring hanger is another say, 2.5' back). So actually the rear spring hangars will see about 1250lbs total. Divided by 2 springs, each spring will feel like it has an additional 600lbs pressing down on it....roughly.
It's hard to explain, but again, hold 50lbs with one hand, hanging down at your side (or on your shoulder). Now hold the same 50lbs arm straight out, another 2-3' away. It's still 50 lbs, but your arm and shoulder think its heavier. your truck feels the same way!
