New to it all!!

Even with larger TVs a WDH will improve the ride quality.  When we bought our Suburban I tried with and w/o and decided to keep using it.

Recently replace a 2005 Tahoe with which we towed our 171 over 15K miles. Although with the longer wheelbase and weight of the TV you probably won't need a WD hitch. That being said, I did find an anti-sway device to make life a little easier while towing. Good luck with your new toy. Safe Travels.

If you're going to be gone 3 to 4 days max, and mainly (or at least, frequently) staying at national parks, my opinion is you won't need a generator.  I believe two batteries (group 24?) should give you four days of careful battery use. 

New Pods come with LED lighting, which helps on the battery use.  The biggest drain is the furnace, so use it sparingly.  If you need A/C, most generators won't run the A/C, at least without modification (from what I'm told--never tried it, and don't often need A/C).  And besides, most national parks restrict generator usage.  Some don't allow them, while others restrict the time when you can run them.  You could recharge your batteries via your tow vehicle, if you need to.

As far as electric tongue jack, I've personally never seen the need for one.  Raising the tongue with the factory crank is not hard, at least for this 50-something, anyway.  But you can always go with the cordless drill adapter for cranking up the tongue, as well as the stabilizers.

Finally, you state you don't think you'll need a WDH with your Tahoe, which is probably correct (although some may say you'd benefit from one).  But you likely will want to consider an anti-sway bar.  The Pod wiggles enough at highway speeds, especially when semis pass you (and yes, get used to being passed by semis, since you probably won't be towing above 60 or 65 mph).
