I don't know if you have buyers remorse, but you are concerned because you spent a lot of money on a luxury/frivolous item. It was not a practical/rational purchase so you feel a bit uneasy.
The good news is price seems in line at 25% off list. It is a lot of money but it is also the rig you wanted.
Turn off your logical thinking and focus on all the fun you'll have escaping the rat race.
Go enjoy your new RV which leads to the most important financial point.
The only way to get value out of any RV new or used. Regardless of price is to use it. The more you use it the more value you get in return.
So quit wasting time verifying things with us and just pack up and go! It will be worth it!
Enjoy it! Don't Worry be Happy
