I hauled my 30,000lb John Deere 120C excavator behind my 5 ton on my 8,000lb gooseneck trailer. (40k GN hitch) and the truck didnt even sag one bit. I mean look at the spring pack.

would anyone feel comfortable putting 40,000 on one rear 5-ton axle
Nope, and neither would the DOT as previously mentioned.
Bridge formula's typically limit axle loading to 20k, or 34k in tandem unless the axle spread is greater than 96". It's pretty complicated and I don't deal in it at all in my line of work. Just limited knowledge, Timothy obviously knows more.
But quick question are you talking about 40k in pin weight or total trailer weight?
