Anybody using a Gear Vendors splitter?
We have a 2005 Dodge Ram 3500 Quad Cab 2WD SRW Cummins 5.9L long bed, with the 4 speed automatic. We tow a 32' 5th wheel that weighs approx 11k lbs. This transmission is essentially a 3 speed with an overdrive. The distance between 3rd and 4th is too wide to keep the engine in the sweet spot of the torque curve on long grades. I have to drop down to 3rd early and often, necessitating dropping back to 55 mph.
I am considering a Gear Vendors over/under so I can split the difference. I am convinced from reading their literature that they do exactly what I need done but I have read in the Dodge hop-up forums many complaints of unreliability. Does anybody have experience with this product in a heavy towing application? I am curious about reliability.
