One of my coworkers is a blabbermouth and thinks he knows everything. He keeps telling me, anyone else who would listen and some that don’t if you’re getting an RV, your first one should be used.
He rarely if ever follows up with answers like “why?”
I thought about it because my first RV was a new one, and I’ve never regretted it. Meanwhile, he purchased a used RV, a 5th wheel and it gave him all kinds of problems. Once he was towing it and the awning deployed. Yes, the awning. He had to find some tie down straps and strap them around the entire trailer to get where he was going. The air conditioner kept going out … this is Texas and you can’t have that! I’ve not had a major problem with mine.
You can indeed have problems with your first RV if it is new, but you have to know the systems. If you have mechanical ability or you are a good student in that area, you’re probably going to be ok.
I carry a tote containing spare parts for RV systems. Check this out: we had our lock go bad, and we couldn’t get in the thing. We did manage to break into it, but once we got inside, we couldn’t open the door. While my wife took apart the lock from the inside, I retrieved the spare lock I had in that tote. We installed it and it was like nothing happened.
You have to be ready for stuff like that.
