suggest Toad for a BT 5230

[zoombats]

Hi. New member here. I have a 2004 450 super duty Bt 5230. I love it and even though I bought it because of its size I still feel a small flat towed vehicle would enhance our use as we could stay put longer and do a little exploring with our two dogs if we had a fuel efficient car to do errands. Has anyone flat towed a vehicle with this rig? I am kind of partial to geo Trakers, or sidekick but would consider any other suggestions based on experience. I realise that I would compromise my already tight fuel economy but would still like to consider it. I am trying to stay below 3,000 LB. curb weight. Thanks ahead.
