Jim, if you check axle loads with and without the WD engaged, I would be interested to see how much load you are transferring.
1979 Boler B1700RGH, pulled by 2004 Toyota Sienna LE 2WD Information is good. Lack of information is not so good, but misinformation is much worse. Check facts, and apply common sense liberally.

I too will be interested to hear what the scale numbers are. Also will be curious to hear if you feel the need to weld the brackets to the trailer frame, or if not, if you any problem with them moving.
The brackets did not move and the trailer stayed true throughout 20-30 mph gusts on the 10 hour drive here to Tennessee. Some of the Casita/Scamps complained of horrible gas mileage due to the windy conditions. I was able to average 14-16 mpg which is better than the Dodge Ram's 12mpg. I removed it within 5 minutes, very easy. I'll report again on the return trip home for ease of hook up, sway, and mpg with the FJ Cruiser.
We also have a FJ Cruiser. I have towed a old Scotty for the last few years that was 2500lbs with no problems. The Scotty is sold and we have a Scamp on order I believe its going to be tongue heavy Because of two propane tanks and front bath. I bought air bags just in case am I worring needlessly or will I need some thing else. Oh Its a 16ft
The issue with the air bags is it involves dropping the rear to remove the springs to remove the rubber bumper inside the springs(where the air bags are then installed)
I opted for the Andersen to eliminate a 1" squat with the Escape's 350# t/w.
I'd purchase a Sherline t/w scale or you can borrow mine to measure your Scamp's t/w. I believe the Scamps are not as heavy as the Casita's are. Once you hook up with the FJ see if there is any squat. If not, your will be fine.
On another note, I just installed some new PIAA fog lights on the FJ, really helps at night. Pictures to follow later.
Just got back from 1400 miles towing with the Andersen Hitch and must say it was pleasant. I had 20-30 mph cross winds and never felt a thing. The hitch performed flawlessly and you did not know it was there. Once at my destination you loosen the chains, pull one pin and you are unhooked. This am I reattached the unit in less than 5 mints for the trip home, again it followed the tug like a shadow. Some of the roads were hairpin "S" type and I had no issues.
The FJ averaged 14/15/16 mpg which is better than the 12 mpg I get with the Ram. With less than 2500 miles on the FJ it should only get better. The terrain was mountainous going and coming.
I've read of some very isolated situations where a couple of folks with Andersens and heavier trailers (who must cinch up those chains quite a bit) had a problem with their coupler. IIRC the pawl that keeps the socket on the ball got damaged, and the socket was riding up partway off the ball. The solution was to replace with a Bulldog or similar, because it clamps down differently on the ball.
the heavier the tongue, the more one must tighten the Andersen's chains to distribute the weight. The chains draw the back of the socket tight against the back of the ball. The people who had problems (I only read of two, I think) had tongue weights much higher than ours. I kind of doubt that we would have such troubles with our lighter tongue weights, but I mention it in case you want to look at it from time to time.

There was a disclaimer in the package that it will not work with certain trailer couplers, mainly on Airstreams. Luckily, Escape does not use that type and with 350# of tongue weight,it was easy to raise my FJ rear and lower the front. The sway control is great as is removing and installing the entire unit.
