To try to understand so I can answer your question: When you changed to the Load Range E tires - Did you increase the inflation pressure to 80 psi? If not, then you didn't actually change to Load Range E tires. You changed to "Load Range E tires running at Load Range D conditions" - essentailly running a Load Range D tire.
The "Es" run at 80psi.. all truck & trailer tires run the max PSI (80 for "E" or 65 for "D")
Like Winky.. I remember towing a single axle Wilderness up and down the East Coast with 35psi in the OE tires.. from tire age of 3yo to 9yo with no issues.. and now my "jack stand" tires are 1996 "C" Marathons that ran 7 years towing and still hold the trailer while the "good" tires are being serviced.
Tandem axle trailers load tires much more in lateral than single axle trailers. I have limited data that suggests 24% more even with the same scale weight.
The regulations will never change unless there is enough data and hard facts made available to NHTSA so simply complaining to other RV owners will not accomplish much.
