Reese Trunnion Bar Recommendation for 740 lbs of Loaded Trailer Tongue Weight

Question

Question:

I have a 27foot trailer with a tongue weight when loaded of 740lbs. Can I use the 1500lb trunnion spring bar RP58369 for this or do I need to use the 1200lb RP66009 for an upgrade? I am currently using the 800lb TW trunnion bars. Thanks

Since your loaded tongue weight is only 740 lbs you want to go with the 1,200 lb bar, part # RP66009, as this gives you a tongue weight range of 600 lbs - 1,200 lbs which is more than enough for your towing setup.

If you went with the 1,500 lb bar # RP58369 it would give you a tongue weight range of 1,000 lbs - 1,500 lbs so the weight distribution system would be too strong unless you plan on loading at least 260 lbs of cargo behind the rear axle of your tow vehicle.

Yes! The trunnion bars for the 1,200 lb and 800 lb Reese Strait-Line weight distribution (WD) systems use the same head unit so they are interchangeable. I recommend going with the 12K system #RP66074 since it already has the tongue weight (TW)…
