So I've taken about 2 weeks to move across country. I've been towing a 5x8 u haul trailer and a bed full of stuff. Is the weight going to bend the springs even the slightest bit? I don't want the rear to be any lower than it was prior to towing. I'm sure I'm just over thinking, but looking a my truck I can tell the rear is down about an inch from the weight on it. It doesn't sag at all, In fact, it's still 2" higher than the front since I have 4x4 blocks and I'm 2wd.

I'm guessing once I take off the weight it'll spring back to where it was?

 

yah no need to worry unless you are overloading, or are holding the weight continuously, like a work truck would with tool boxes and ladder racks etc.
