Do people "test drive" a trailer before purchasing it?

We bought a Tahoe so we can tow a travel trailer, but we've never towed anything before and are a little concerned about how hard it will be.

Trailmanors should be easier than others due to enhanced visibility and reduced air resistance. And we love the fact that we can put one in our garage.

Do people ever test drive a trailer before purchasing it? We're smart, capable, and educated. Just don't want to end up with an expensive item we're not comfortable towing and have no way of knowing if for some reason we'll find it challenging.

In talking to dealers it seems they would let us test drive one if we're serious about buying it, but haven't found a 2720 TM at a dealer. What do private sellers thing about newbie trailer owners and test drives (or the option to return the trailer within 24-hours if we're not comfortable towing?)?

Any ideas to help us feel comfortable with our purchase while not alienating potential sellers would be appreciated!
