When, or if, it ever quits raining I will roll under the 5th and do some measuring. I'm thinking distance from the driveway to the axle tube at the center, and close to the springs. I don't know how much they are supposed to be bent up at the center. I'll check for about the same measurements on both axles.
Start with a framing square and a level I think.
I don't believe it is a severe condition. Probably will be good until time to replace the tires. Just rotate more often on the next set.
