To the tandem axle, the trailer seems to be a very large double dual. Tandem axles, by the way, are not unusual. The trailer, which has the greatest 24 Inch Rims, is definitely maxing out the Toyota by itself, in my opinion. People have stated that I am slightly disappointed, so it's more than that. I gained twenty percent with twenty percent more weight as I ascended seventy-three hundred feet. I'm then expected to carry. And it survived, so I'm not sure how it's doing. However, they slightly overloaded it. By the way, a long time ago, I had one encounter towing the hybrid. My wife, who enjoys off-roading, purchased a Prius when gas costs dropped to $5 per gallon.
