Marc,
I don't know.... 5.7 Hemi might be a little underpowered (just kidding).
While many don't use a weight distributing hitch, I still use one to restore weight back to the front axle to maintain safe braking and steering. Also, I've found that towing is more comfortable with a WDH, especially with a tongue heavy trailer like the TM.
Because you will likely have hookups wherever you go, as long as you are towing safely, you can probably get whatever you need if you forget something on the way. That has been my philosophy, anyway. That said, I've made some checklists that help me figure out what I want to take. Here are some manuals/checklists right on this site:

If you haven't paid for a subscription to this forum, it is well worth it. No one advertises here, just lots of free help and advice. In fact, it was because this forum existed that I finalized my decision to get a Trailmanor.
I'll attach my own version of a checklist. This one has been tailored to my needs, including large print towing checklists that I laminated for use every I pull out with the trailer.
