So, I've been out 3 times pulling the 29' jayco featherlight with my Dodge 3500 cummins diesel. Pulls like a dream, went to the trailer hitch specialist shop where I live since I already had the WD system. He looked at my set up and said there is no sink whatsoever and told me it would save me the money not having him weld the reese weight distribution system on, as the 1 ton carried the TT with no drop and all was level.
I've not found any sway while pulling the trailer so far. But it's funny what you worry about at night. Does anyone ever worry about the stock receiver system on the truck that you attach your ball to in order to pull? I'm running on the assumption that Dodge designed it well since it's a 1 ton. Am I correct? My trailer is not heavy, but I am going to pull it to the west coast this August over the Rockies and the Coquihalla..
