We have a Minnie 2201DS with the outdoor kitchen. Bright yellow, you can see it a mile away and it gets tons of stares and comments (mostly positive). After 6 trips (36 nights) so far this year, There isn't one thing that we have found that we would change. Tons of storage space, easy to tow, quality construction and that giant blank back wall just begging for you to get creative with a decal of your own design (or what ever you can find on-line). We were never asked about a paint protector, it may be a "pure profit" item for your dealer, but everything I have read about the gel-coat TTs says just wash and wax a couple of times a year and you will be fine.
DW and I were so impressed with the Minnie, that we traded in our 1-year old trailer to get the Minnie. So far, it seems to be a TT that will last us for a long time to come.
