new to the forum and soon to RVing.. and have a question...

You're making a newbie mistake by only focusing on towing capacity.
You'll run out of payload capacity WAAYYY before you get near the towing capacity, especially with a SUV.

what's the driver door sticker say is the payload capacity of your vehicle?

With a DRY tongue weight of 940lbs, I'm sure that loaded, it will exceed your Infinity's max hitch capacity.
And NO way would I tow a nearly 34' TT with your vehicle.

I suggest you scale down your TT choices.
