I towed the 4000lb S10 on a tow dolly with the Cummins Dodge yesterday. I had the overdrive off. It towed just fine. Set the cruise control to 55mph. The brakes on the Dodge are not a good as the van. So I do need to do a brake inspection when I put in the new KYB shocks. I”m thinking of putting in synthetic fluids in the trans and diff.
