Newbie - Which is better tiny bunkhouse or hybrid

Look at the sticker inside the drivers side door jamb. It will tell you the cargo capacity of your Sorrento. Then add up the weight of occupants and cargo that you will have in the vehicle, and that will tell you how much capacity you have left for the tongue weight of the trailer.

Then take a look at the hitch receiver. There should be a sticker telling the tongue weight limit of the receiver.

I suspect you will find that the Sorrento is not as capable as you believe it to be.
