Thanks to everyone for posting!
To all who suggested a bigger tow vehicle, I agree that bigger would be better - higher load margins, more payload, possibly better brakes. A 3/4 ton truck would tow this TT really easily.
Originally the Audi was the only vehicle that fit our needs back then(four years ago). It was an adequate tow vehicle for the 2150, it had three rows so they’d be room for the grand kids, and it fit in the garage.

Well time moves on and the DWs new car bumped the Audi to the curb, parking that is. So now there is less reason not to get a truck. Oh well, I’ve never owned a truck so I’ll try to run a few more camping seasons with this setup.

Thanks again to all and Happy Camping!!
