We have a new 2013 28BHBE, we are towing it with a 2012 F150 5.0 XLT 4x4 Supercrew. Our trailer as optioned weighs in at 7068# according to the decal on the door, take a look at yours because the trailer options add significant weight. We are using an Equalizer 1k/10k WD hitch.
Your tow capacities are not too far off from ours, I might have a bit more payload at 1625#. We haul very little fresh water, just so the kids can use the potty if there is nowhere to stop. We travel with the other tanks empty. We generally do short trips, 200 miles or less.
I think you'd be fine with a WD hitch set up correctly. Don't haul anything that you don't really need, try to keep your weight as low as possible.
