Any financial advantages of buying new RV vs used?

If you are not handy and DIY type of person, buy new otherwise buy used as there is many low mileage units for sale from folks that did not like the lifestyle or used it enough. The major item with used is copy of records which really helped with the sale of my last unit since I kept all records and when I bought a newer used unit, all the records were part of sale. I saved almost 50% buying late model used vs same model new. I would never buy new again.
