I have been towing with Unibody Vehicles for years and not one issue. I will continue doing so as they are fantastic handling, lower CG, better breaking vehicles.
I would reinforce the hitch and continue on. The work should cost you less than $400.00...and you will end up with a hitch stronger than what's on most trucks.
Think something like the picture below. This is how Can-Am RV in London Ontario reinforce a hitch on a Town & Country and most hitches they reinforce.

But, if you want a truck... that's a viable option too.
Thanks!
