Speaking of drawers, unless you order the convection microwave, you will not get ANY drawers in the galley (for silverware, etc.)...an unfortunate compromise for a trailer that size, but at least the convection microwave is a worthwhile addition, as is the 2nd air conditioner and the streetside awnings.
Insofar as visiting the national parks, don't sweat it...if it's worth seeing, there will be adequate accommodations either in it or near it.
Finally, although we tow ours with a 1/2 ton, we travel pretty light, and rarely even have any passengers. However, if you plan to routinely bring kids, grandkids, bikes, generators, grills, etc., you probably need a 3/4 ton tow vehicle.
You mess with me, you mess with the whole trailer park.
