Like I said above, the Armada's limitation is in its payload. Go look at your tire loading sticker inside your drivers side door for this sticker. From that number you will need to subtract all occupants, cargo and pets that will be in the armada when towing. The loaded (not dry) tongue weight will need to be less than this number. Ideal loaded tongue weight is 13-15% of loaded tt weight. Now, there are two ways you can guess where this will land for you. First, on average people tend to load approx 1000-1500 lbs of stuff (food, clothes, dishes, chairs, tools etc) into a trailer so you could add that to the dry weight and figure 13-15% of that number. Second method, you have a tt already, go weigh your current set up to figure out how much stuff you add to a tt and then calculate potential tongue weight from there.
When weighing, easiest is to go to a local cat scale
at a truck stop or you could find a feed store or dump station willing to do this. You will want to have the armada loaded with a full tank of fuel, all occupants, pets and gear you usually take camping and have your stuff in the tt as well. You will do 3 passes (can be done in any order). First pass, armada only. Have front axle on scale pad 1 and rear axle on scale pad 2. Second pass armada plus tt no wdh. Armada as in pass 1, all tt axles on scale pad 3. Third pass, armada plus tt with wdh. Set up same as in pass 2. Third pass is more informative of how well your hitch is set up. Since you are trading, you could skip this step for now but recommend doing for your next tt.
From the first weigh, you now know your individual axle weights and your true weight of the armada. Take the armada's gcwr and subtract your total armada scaled weight to get your adjusted towing capacity. Your loaded tt weight needs to be less than this number. Take your total armada scaled weight and subtract it from the gvwr to get your available payload. Your loaded tongue weight needs to be less than this number. Subtract the rear axle weight from the gross rawr to see how much room you have on your rear axle. The wdh will transfer some weight off your rear axle so this number is ok to be slightly less than gross rawr but not too much.
Second pass shows you loaded weights of your current tt. Subtract the weight of the armada in the first pass from the total weight of the second pass to get your loaded tt weight. Subtract the weight of the armada in the first pass from the combined drive and steer axle ratings to get your loaded tongue weight. Now look at your current tt's unloaded weight (yellow sticker in tt either door jamb or cabinet) to get how much stuff you add to a tt.
You can now add this weight to the unloaded weights of tt's you are looking at to calculate an approximate loaded weight. Calculate 13-15% of that weight for loaded tongue weight and you will have a more accurate idea of whether or not you will be within all towing specs of a vehicle.
Good luck and happy shopping!
