Does a lower profile tow better? NOT a mileage Question

The only difference we've noticed about our sloped-front Bullet is that there's less overhead storage space for our foldable clothes over the bed. The slope eats into that space. There's also less head room sitting up in bed. Fortunately, my husband and I aren't tall, and we don't tend to read or watch t.v. in bed, so it's not a big issue for us.
