Good afternoon John
I can help you as I was a test bed for Reico Titan jacks a few years ago. They wanted a heavy T/C (Lance 1172)and we replaced my Atwood jacks one at a time with a Reico Titan jack. The R/T jacks tracked perfectly with the Atwood jacks in all configurations.
Also an added bonus is the R/T jacks are a direct bolt on with no additional hardware needed.
R/T does recommend you purchase 2 jacks at a time.
So sitting in my shed is 4 Atwood HD jacks.
Thats my truck and T/C in the Truck Camper Magazine article.
