2004 2WD Limited rear suspension

[Rickwtexas]

My 2004 Sequoia (216,000 on odo) rear height suddenly increased (overnight). It's drastically affected the handling, even though I'd estimate the additional height is 2"+. Since an 04 does NOT have an air suspension, I'm assuming one of the shocks gave out and took the other one out at the same time? I do pull a small trailer (about 1500lbs) two weekends a month and the extra weight doesn't make the Sequoia ride any better (I thought the weight would stabilize the rear,,, no).

Any feedback is appreciated. Thanks in advance

I'm thinking I've been 100% opposite in my reasoning... maybe the front has dropped
