As far as payload goes. My family weighs in at around 568 lbs. Dogs at 100 lbs. 85ish lbs. for hitch. Probably <100 lbs. miscellaneous in the TV.
2561 payload (are my numbers correct for 2008?)
-853 lbs
1701 left for TT tw
1512 payload (7.3 PSD Ex)
-853 lbs
659 left for TT tw
Just rough estimates of course. And I understand the Ex's can handle a lot more payload, especially with upgrades. My question is, what are the legal implications of these upgrades are not certified to increase payload. I have seen very mixed feelings on this.
Edit: only considering payload. I understand a hitch upgrade/mod would be in order on the Burb.
