Thanks for your insight Bmwbob, this thread has been so helpful since I am in a similar situation. Would you think the Rav4 Hybrid limited would be sufficient to tow an airstream 16RB trailer? I love the gas mileage on the RAV4 and would hate to have to trade it in for an Adventure package Rav4 since it means I would lose what attracted me to the Rav4 to begin with. It seems like it is mostly a legality issue and not a mechanical or electrical issue having the towing capacity rate at 1750 and not 3600 lbs like the European standards. I am looking forward to see how the improved hybrid system with more power affect the towing capabilities of the new 2019 version in hybrid models.
I agree completely with Octane and would hate to see you HAVE to trade in your wonderful Hybrid because you burned it up trying to tow WAY over it's capability especially at Texas speeds, meantime getting :egad:5 MPG!Airstream 16RB is 2800# dry, so about 3100 fully loaded, and 8 foot tall. nothing comparable to a tab trailer that is almost half the weight and a lot more aerodynamic.
I tow a 3000# trailer with the V6 and it's borderline some times, I would not consider towing more with the hybrid! EURO ratings are higher because tongue weight is lower over there and speed while towing are also lower.
