My DW loves driving and towing with HER dually. It is her daily driver and she loves the looks many other guys and girls give her when she climbs out of it. It is also a good excuse to get more exercise by parking in the back forty and walking into the shopping stores.
we both love the stability while towing over our F350 SRW.
I'm with you. Get the dually and she will appreciate it after you have towed through a couple go strong wind storms and had to make a couple quick lane changes to avoid a situation on the highway while towing.
