I already posted this on a new Landracing Forum, but wanted everybody to  
see it.....Thanks !
 
Does anybody have a grip on what the actual realistic capacity for both  
towing AND carrying passengers/gear on/in a Crew type pick up or Suburban  
type rig? All the manufacturer ads tout towing capacity and also passengers and 
 gear, but not specifically if you could actually load up both to those 
claims. 
An extreme example would be a six passenger crew cab, loaded bed, and  
whatever the maximum advertised towing capacity. Tongue weight is recommended  
like around 10%, so some of the biggest tow capacities around 16K would  
suggest 1600 lbs on the tongue. If it's a crew, that's six @ over 150 lbs  @, 
and the actual rolling towed trailer. That's 2500 lbs, plus, carried and  a 
lot of rolling pull. I'd assume it's either passengers and stuff, or the tow,  
not both. 
Whaddya you think?
