This is an excellent, simple explanation of how much your vehicle should tow,if you follow this rule of thumb, you will be safe.
We went back and forth between the 19h and the X17Z. I would have loved to have the larger trailer, but we tow with a Chevy Astro rated at 5000lbs, and we felt much safer with the smaller one. That being said, even though our TV has plenty of tow capacity for our Z, in the 14 months and 16 trips we have taken, we would like even more tow weight capacity, even with the Z. We intend to upgrade to a Chevy Express 2500 next year as it will have plenty of capacity to tow our Z, and would give us plenty of wiggle room if we did want to move up to the 19h.
I know people do it, but I am not even sure I'd be comfortable towing the Z with a vehicle that had a 3500 rating. Just a little too close for comfort for my taste.
