That's really close to my fifth wheel weights; 6250/1250 dry weight. Keep in mind those weights will increase when you load it up. I'm at 7500/1250 mostly loaded, actual weights.I need someone to tell me about towing a 5th wheel RV with the Tundra 5.7. I have a 2008 tundra , looking @ 5th wheel with dry weight 7545 and hitch weight of 1125. Would welcome feedback.
