I saw your question in my post, so wanted to answer you and maybe give others looking at the Roo 19 the info to consider too. My Tow Vehicle is a 2011 Nissan Frontier Pro-4X CC, 5-spd Auto, 6100-lb tow rating. I will use an Equalizer Hitch and Prodigy P2 Brake Controller. Disclaimer - These weights are all theorhetical since I don't actually have the trailer in hand to weigh. Also I may be forgeting some things but I believe some of my listed weights are on the high side.
Weight of Fuel (21 gal tank full) = 175-lbs
Weight of Passengers = 325-lbs (wife, 2 kids, 2 dogs)
Weight of Personal Gear = 300-lbs (clothes, bikes, toys, DVD's, etc)
Weight of Stored Items = 100-lbs (TP, paper towels, dish soap, camp chairs, etc)
Weight of Food = 100-lb
Weight of 1/2 Tank Water = 150-lbs
Weight of (2) Full 20# Propane Tanks = 80-lbs
Weight of Firewood (weeknd trip) = 100-lbs
Weight of Equalizer Hitch = 60-lbs (approx)
Dry Weight of Roo 19 (estimated factory build) = 3650-lbs
Overall Load for Trip = 5040-lbs
This is 82.75% of my tow rating
Hope this makes sense.
