How far can you comfortably tow in a day?

Of course, when we're working, our time is very precious. we try to get to our vacation paradise as quickly as possible so we can savor our time there. With that said, last year, we drove from Tucson to Salt Lake City in about 15 hours (800 miles). We stopped and stretched our legs every 2-3 hours.

I'm retiring in 72 more days! So I can poke along as slowly or as little as I like. A 4-6 hour drive seems more reasonable.
