Redwood 3991RD 17,900 GVWR and dry pin weight of 2620(low for it's size and weight, which is helpful with a SRW). It will we interesting to see you fully loaded scale weights. Do you plan on a W/D and/or gen set?
Hopefully you went for the F350 SRW with 12,400 GVWR. I could not find the RGAWR, however tires limit that to a max of 7500, on edit: found it RGAWR 7230.
Being an advocate of these newer SRW 350/3500 for towing larger trailers, I interest in how this works out for you.
We full timed for almost two years load heavy(16K trailer) and made weights, except for being 40 lbs over TV GVWR, however was licensed for more in my home state. I do know that a washer and dryer would have put TV rear axle over, and a gen set, way over.
