WD Hitch - Selection Questions based on TW and GVWR

UPDATE:

Purchased toyhauler today (2009 Tahoe 284SA)!!!!

Weighed TW today...

TW dry (water/waste tanks empty, nothing stored inside or outside ot trailer....

First weigh: 1400#
Second weigh: 1500#

Average: 1450#

So, based on the 1450# TW.....what hitch is recommended?
Keep close to the 1450# TW....(ex. Equal-i-zer) or go with a higher weight rating?

Examples.....

Equal-i-zer 1400# (had two before and both worked great!)
Blue Ox.....1500# or 2000# (never had chains....reliable and sway control?)
Reese?????

Thanks!
