Congratulations and welcome!
29M is a nice RV and floorplan. Dont stress about stuff that hasn't happened or might go wrong, focus on the fun you're going to have and what could go right!
You are correct that there is a lot of bad out there but it should help to keep it in perspective when you factor in that there are more Thors out there and the people most likely to post stuff are those with something to complain about (vocal minority, like in politics)
I've had my share of problems and complaints too and while occasionally frustrated by some design, quality or service issue, overall we are happy and always look forward to our next trip!
