Now that you are back on the level, I'd lay a Andersen Leveler between the wheels on the side that gave you grief on your last trip, and see if there is room to put it in there.... Then, take the same leveler to the other side, and see if the clearance is the same. If not, you likely have an issue. If it is the same, you are more than likely ok, and I'll take a guess at what happened over the weekend.
IF there is a hump in the ground or gravel between the wheels, then when you lay the leveler in place, it has to cam up the opposite side - which in turn makes it contact the tire sooner, as the radius of the tire means the treads come together the higher from the ground you are. Make sense? Clear as mud?
If there wasn't a hump in the ground between the wheels, then we need to dig a bit deeper.
If the above test (seeing of the sides are the same), and you find they aren't, I'd be looking at the spring hangers and either you have one that's bent or the weld is broken and it's hanging crooked.
Report back what you find.
