As said above, Welcome! I pull my 07 3814SS with a 2500HD Dmax myself (crew-cab/standard bed) and haven't experienced any sway issues, but i do use the W/D system i had on old camper (Ezy i think it is).. Love the trailer and full timed in it a few months last year when changing jobs/moving. Pretty standard on the options i believe, but mine happens to have the atrium windows. We love 'em, but did change to mini blinds on some of the windows due to their length and having to reach behind everything.
Our 1st bed also had a support issue, so after the 2nd warranty service they gave me one of the newer airbed styles with the storge drawer. That's handy!
Welcome, and enjoy the new camper!
