I have no idea what happen with your would probably work if you had 4000# axles. That could be a course of action...switch to 4000# axles...don't think to would be too expensive. Try to get some pricing from Dexter and Lippert.

I think you'd be better off buying axles from

At the moment I am switching to "d" rated tires which will give me over 8000lbs tire capacity. I will load carefully to try and stay under the 7000lb axle rating.

My chance of tire failure is minimized. If there is an axle failure I will be talking to Forest River about their underrated tires and axles. Since I will probably never exceed about 7200lbs on axles I am not to worried about it. I am sure there is a margin of safety built in to the axles.

Fifth wheels are new to me so this is an interesting exercise. All the heavy stuff-water heater, fresh water tank, frig, slide, and most of the storage is near the center of the trailer. There is not much in the upper portion except the bath. So I think it is virtually impossible to load to maximum and have 2350lbs on the tongue.

I don't know if this helps you, but my 8285 tires are 225's from the factory.

Well my outside weight and tire sticker says 205/75/15. Plus the existing tire clearance would make 225's iffy.

Mine made in 2008 - Rated load about 9300 - outside sticker says 3500# axles and 205 tires. Have changed to 205 tires "d" rated.

Add 40 gallons of water and you are close to the limit.

Your weights look pretty good to me, I am new to 5th Wheel but have been in trailering since the 70's. My trailer is 2013 and has the 4000 lb axels and with 225 tires there is 1 1/2 to 2 inches above the tires. I am thinking of getting smaller D rated tires as well. Need to look at the height of the trailer vs pin on the truck to see if smaller tires can be used.

My real problem is the sticker weights versus reality. Gross weight 9300lbs - axle capacity 7000lbs - pin weight necessary to not overload axles 2300lbs. Don't see anyway you could load to 9300lbs without exceeding axle capacity. I am within about 200lbs of axle capacity and have about 1800lbs of pin weight. So most all of additional weight would have to be pin weight. If I added any water or had a bit in the holding tanks I would exceed axle capacity.
