Potential TT owner looking for advice

Without getting into the ability of either vehicle to tow 5000 lbs consider the tongue weights. You show DRY tongue weights of 325 for instance. Now add just a single full propane tank and a battery to that tongue. Your over 400. And what other items or people are supposed to be going in the SUV with you? Or if you prefer consider the GVWR of around 5000, The rule of thumb for tongue weight is 10-12% of that so with that you are over 500 lbs.
Without knocking either trailer your choices of tow vehicle are very limiting.
