I've heard a few people remark that they have a "covid unit" - implying there have been some QC issues as employees came and went, so based on that, the used unit might be more problem-free (assuming the original purchasers dealt with the usual gremlins that pop up in any RV)
But that being said - I own a 2023 Thor 22E. Its main trip was from Michigan to Florida, plus a bunch of small side trips - and it's been perfect. No glitches or problems. We added a Safe-T-Plus steering assist and a Steer Safe trac bar - it was perfectly fine to drive without those, but now drives like a rock-solid sedan instead of a big truck. Personally, I just like the "feel" of a Class C (plus the safety features built into the chassis); and the new Ford 7.3 motor has plenty of grunt!
