JJ - Thanks for the comments and info. As you stated in your edit, the Venza cannot be towed at all. We bought the car before the MH so towing wasn't even a consideration at that time. There are many vehicles that can technically be towed and I have seen them towed as well, But, if the manufacturer says no in the manual, you are on your own if/when something goes wrong. We looked at a Honda Fit which I have seen towed, base plates are available, etc.. BUT, Honda says 'No', so the warranty will not cover any resulting transmission or other issues if they can point to towing as a possible cause. Even Remco says that many people do tow the Fit without problems but "if you have any trans damage you will pay out of pocket". I just don't want to take that kind of a gamble.
I think we have pretty much resolved that towing 4-down is the way to go so we'll just have to bite the bullet. DW is still thinking that renting a car is cheaper - may be right but I really want a car with us for all of the convenience it offers.
