Can I just upgrade to 5200 pound axles ?
OK...example; I have a trailer frame with dual axles rated at 4400 each. The frame design is well built with a tubular frame. So lets say the axles are rated for 4400 each now and I have 15 inch E rat...

Could I safely upgrade to the 5200 axles to give me a 10400 max load rating vs. the 8800 I have?
No....nor would 6k axle make your 8800 gvwr trailer into a 12000lb gvwr trailer.
10k gvwr RV trailers has the trailers shell (sidewalls/roof) strengths figured into its gvwr formula.
Trailers like a 10k gvwr car hauler/flatdeck and equipment trailers have a stand alone frame.
Take a look at a 10k gvwr stripped down rv trailer frame that some one thought would make a 10k gvwr car hauler.
The main frame rails on the 10k flatdeck trailer are much heavier plus it has close spaced crossmembers vs the rv trailer lightweight frame that would do well to support a 3000-4000 lb load.
Going to 5200 lb axle will give you a 6 lug axle for 16" wheels and LT E tires for 40k-60k miles and 7-10 years of trouble free service with the right tire maintenance. Check with Rockwell American axles or Dexter axles if going up to their 5200 lb axles would be a brake upgrade.
