We've been in our wonderful 369RL full-time since April of this year. We are really enjoying it. No major issues thank goodness. Since we've arrived in Kentucky for our stint working at Amazon, we've noticed a popping sound, and have determined that it seems to be coming from the front level up jacks. I've found this is a fairly common issue across all brands for the level up system. Has anyone else here noticed it with their Solitudes? Thanks!
