I would get a weight on the Ridgeline, full tank and packed as close a practical as it would be when towing. You want a weight for the front and rear axles. While the CAT scales at any trucks top can do this, a local co-op or gin in your area may not be so busy. The co-ops generally have a single platform scale so you pull on up to the rear axle to get your front weight, pull forward to the center for both. Subtract the front from total and you have the rear, or you can weigh the rear separately. Go back with your trailer in tow with whatever water, etc. you normally carry. Repeat the above steps to get your Ridgeline's front and rear weights again, then pull on completely to get the combined weight. Again, you can subtract the Ridgeline's 2nd total weight from the truck and trailer gross weight to calculate the trailer's axle weight or you can pull forward so that only the trailer is on the scale.
From this you can determine if your WD hitch is set up properly. For round numbers, if your tongue weight was 600#, you would like to see a 200# weight gain on each axle of the truck. A little more on the rear axle is okay. The other 200# went back to the trailer axle(s). Looking at these weights you can compare to the specs for your truck to verify you're not overloaded. Look at the sidewall of your tires for the max weight. If they say 1800#, and you have 3200# on that axle, you're in good shape regarding the tires with some capacity to spare.
