The Caravan Club of the UK has just released a report testing lots of
Euro and Far East cars (and a few American ones) for caravan towing.
Might be of interest, although nearly all of the cars are diesel, so I
guess very few are available in the US.

Note that the lightest caravan towed was 880 kg, compared to Ray's 750
kg laden trailer, pulled by what I think are called "subcompact" cars
in the States. Larger cars were towing caravans up to 2,000 kg.
The last page also lists the same advice on weight and balance you've
all probably grown tired of me listing here :-) - at least it proves
I'm not making it up!
