I do not know for sure how your rims became bent. A side impact, yes I can see this or they where made wrong from day 1.
To your point about repeated tight cornering with a heavy TT like the T2499, This I can comment on and maybe dispel some of that. Don’t know if you saw my post or not but I put 2 new axles in this spring. In doing all that investigation I learned a few things about tandem axle suspension used on TT's.
This refers to leaf spring suspension specifically but may apply to torsion axles as well. Which is yours?
First, the front axle takes more abuse in tight turning then the rear. The turning radius is shorter on the inside of the turn. The back axle sort of drags along for the ride.
Second I would make an estimate that the actual thin spring hangers used are the weak link in turn as opposed to the rim. How I know this is mine are bent. Today I’m out there beaf’ing that area up. I never made it to that part when I did the new axles. In my case I have 9,200# of TT on the same thickness of hangers that are on my T2499 that only fully wet weighed in at 6800#. And on the T310SR they hang down 5” as opposed to the T2499 that are only like 2 ½”.
I believe mine have become bent turning hard in my own yard. And this is not many turns, maybe only 6 to 8 or so as when the lawn is hard enough, I use the lawn as a back on it and turn verses doing a hard 180 on the concrete. The amazing part is it took very little force on a 24” pipe wrench to put them back perfectly level. Which confirmed my point about them being weak. If I can bend them back that easy, my F350 pulling it around the hanger is going to loose. I ahve to find a 4 x 8 sheet of someting slippery to turn on. Tried plywood but that is not much better. This M & G in June I’m going to ask one of the Sunline 5er guys if I can look at there suspension. There axle weights are a lot more then mine and I’ll see what they have. A 5er can turn tighter then the TT
So in all this, I do not think doing turns bent your rims. Your hangers would bend first if you have leaf springs. Only thing I can think of is a side impact or bent from day one. While Sunline was a high quality TT builder, they bought the TT frames. And the frames are made like 90% of all other brands. And in my case I was lucky enough to acquire 2 axles made wrong from day 1. Lucky me. It is not like theses frame and suspension go thru a high quality control final check out before shipped into Sunline. As if they did then they would of caught my issues.
Hope this helps
