Question:

We currently have a 24foot TT ~26.5foot total length with hitch with dry weight of ~4500 lbs and a listed dry tongue weight of approx 570lbs. With the battery55lb, dual propane tanks~60lb, and trailer loaded Im sure the tongue weight is approx 700lbs. We are currently running a Reese WD hitch, straight spring bars, and a friction sway control. Our tow vehicle is a 99 Jeep Grand Cherokee V8 4X4 with tow package 6500lb towing capacity. Im looking to upgrade to a Reese Dual Cam HP RP26002 sway control, which will necessitate me changing out my straight spring bars for the curve end style. In researching the various components needed I believe I have narrowed it down to either Reese RP22225 which are listed as 800lb but have a range of 400-800lb. The other option I see is Reese RP66009 which are listed as 1200lb but have a range of 600-1200lb. Given a tongue weight of approx 700lbs, which spring bars would be best? Additionally our hitch setup is 7 or so years old. The heads of the spring bars I listed above appear to be the same style trunnion bars as the straight bars we have today. Is there something we should measure to ensure the new bars would work?

The newer spring bars will not fit in the old style heads so you would need to replace the head as well as the spring bars. If you go that route than it would be better to just replace the whole system and get all new parts, because the cost is about the same.

If you go with a system rated for 400 to 800 pounds then it will cover the unloaded and loaded weight of the trailer whereas if you went with a 600 to 1,200 pound system it will only cover the loaded weight but does allow you to tow something heavier in the future.

For a 400 to 800 pound system you can use # RP66073. It does not include the shank but you can use your existing one. The dual-cam sway control is included. If you need to add a ball then you can use # A-90 for a 2 inch and # 19286 for a 2-5/16 inch.

For a 600 to 1,200 pound system go with # RP66074. Again the shank is not included but you could use the old one. And the same balls listed above will fit this system as well. I have included some instruction links and videos for the Straight-Line system for you.

If you did want to replace the head you would use # RP58167. Then for a set of 400 to 800 pound bars use 2 of # RP22225. For a set of 1200 pound bars use 2 of # RP66009. Then you would also need the dual-cam system, # RP26002.
