I have not towed with my Armad yet, but I will be towing a boat with a bunch of gear. It will only total about 4,000lbs though. I ma pretty sure the Armada will tow it better than my Silverado (4.8 motor) though.
I tow a 6x12 cargo trailer that weighs in around #6500 fully loaded. My Armada pulls it like nothing!
Way, way better than my old Tahoe with the 5.3. I even had my Chebby modded with a CAI, hypertech programmer, Granatelli MAS, and a Corsa cat-back system. It still didn't even approach the power of the Nissan.
21' Outback (in my signature) averages around 5,500 lbs loaded. We're looking at moving up to a 26-28' Outback that will be more in the 6000-6500 lb. range. The Armadas (and the Titans) are great tow vehicles.
26' Prowler Lynx 826M Ultralite, 4300 dry, 5500 loaded. Equal-i-zer weight distribution / sway control hitch, Prodigy brake controller. Great tow vehicle! Quite a bit better than our previous tow vehicle (99 Durango).
I tow my 23ft Chaparral 230 SSI -- and it tows great...but I haven't really tested it in the mountains yet -- that will really be the true performance indicator...but won't get to do that till next year. I take it on 2hr trips down to Lake Anna...and it tows with no prob...combined trailer/boat weight...probably near 6500lbs.
Just thought I'd update this seeing as we now have the 28RS-S which is actually almost 29' in length. Dry weight is listed as 5,500 lbs (actually around 5,900 lbs lightly loaded) and max's out at 7,000 lbs. Hitch weight is 460 lbs. Oh, and I HIGHLY recommend the Equal-i-zer hitch ($400.00 from rvwholesalers.com). Absolutely no sway and no "bucking board" when on rough pavement.
We tow Rage’n 2124c #5850 UVW, #800 Hitch Weight. Loaded= #70 LPG + #415 H2O (50gal) +#600 ATV + #450(2MC)+ #100 gas (15gal) + #100 food/drink for a total of about #7600. Toy box can hold 100 Gal of H2O and 34 Gal of gas but I do not see a need to fill for my purpose, except when I leave it at our property(cabin duty)and I fill it locally to lessen tow weight(#8000 ouch ). The rear air suspension pumps up and levels out load great, but also really stiffens rear suspension. You would not want to ride in third row on bumpy terrain! We do not always take the ATV on trips, instead a third MC which saves #400. Tows nicely with no sway but drinks gas like a drunken sailor. Have not checked MPG, too sacred to. I would think that this toy box is very near the realistic upper end of tow capacity. The Armada will only be our frontline TV for about two more years, as my oldest will be driving and I will give him the old 4Runner and buy a diesel pickup for the toy box.
Prodigy brake controller(the best)
EZlift hitch #1000WD
Also tow a bunch(weekly) with a Big Tex LA50 6.5' x 14' tandem utility trailer. #1350 UVW maybe a couple hunderd Lbs hitch weight. Have had 1ATV and 5 MC on it for a total of #3200 and can hardly tell it is back there.
