Hi to all and thanks for all the info we have gleaned so far from RV Forum Community. We purchased a 2017 Passport Ultra Lite 2520RL TT this summer but have yet to take it farther than from dealer to our storage facility. Our goal has been to snowbird Husband and I have a 2002 Chevy Tahoe Z71, 4 WD, V8, 5.3L. Our concern is about tow capacity of the Tahoe and general payload estimate for a couple with two small pets. The spec max trailer weight with a weight distribution hitch (we have one) for our vehicle is given as three weights... 7400, 8100, and 6400 lbs. Why the difference and which weight should we use? Our trailer has a dry weight of 4930 lbs. and a hitch weight of 550 lbs. The GVWR for the trailer is 7000 lbs. Our question is do we combine the hitch weight and dry weight before adding payload weight? We're new to this and wonder if 1000 lbs is too light an estimate to carry our stuff. Thanks for your feedback!
