Question:

I am upgrading my trailer to a larger and heavier model. I have a fastway e2 trunnion hitch with the 800 trunnions. The new trailer has a tongue weight of 880. Gross weight under 10k Which trunnion is the best match? I am towing with a Silverado 1500 with max trailer and duramax engine

Thanks for reaching out, Winston!

If the 880 lb rating is fully loaded then the 1,000 lb Bar # FA92-02-1099 would be what I recommend since it gives you a tongue weight range of 600 lbs - 1,000 lbs.

If that 880 lb rating is unloaded then you'll want to go with the 1,200 lb Bar # FA92-02-1299 for a tongue weight range of 800 lbs - 1,200 lbs.

These parts are only the single bar so you'll need to order 2 to upgrade your system.

Hey Winston, how did the new trunnion bars work out with your heavier trailer? It’d be great to hear which option gave you the best balance with your Silverado. Your update could make it easier for the next person upgrading their setup.
