I did the E track system because when I tow behind my fifth wheel I need less than 500 pounds tongue weight, hence the back in. When towing behind the truck I can handle all the tongue weight the trailer can give me. It makes a difference in trailer tracking true to tow vehicle. Towed over 4000 miles last year when I went out to Oregon last year without issues. Only bug in the system was Oregon does not allow double towing. I dropped SS trailer in Parma Idaho at cousin house then pull fiver to Portland, then dead headed back to Parma to tow SS trailer out to Portland. Had to reverse process when I left for home 6 weeks later. Due to Oregon's law it added a full 24 hours of driving and 1600 miles to my trip. Kind of pissed me off so i made sure to fill all tanks in Parma coming and going, just trying to beat Oregon out of all the fuel taxes i could. I can pull triples on my CDL in Oregon in a commercial truck but only one trailer when in a recreational vehicle. And according to my correspondence with several agencies in Oregon they dont really care about all the money the state is loosing from RVers that tow a small boat, ski doos, bikes, or any tag trailer.
Dang, guess I vented, sorry
