Looking at an X...thoughts?

Thank you all so much! Hubs and I are new (obviously) to the towing world, so just learning the lingo, abbreviations, equations, etc has been overwhelming at times. I feel a lot more confident now with an Excursion being a contender. It's either this, or an E350 we are looking at. Now I just have to figure out tongue weights and I think we will have this somewhat down.

I need a Towing for Dummies book... lol
