I had the dealer add 3 more holes to my Yetti, and will probably add an AC or a fan this summer, done by a dealer. The reason I didn’t do it myself is because I’m just not good at that stuff, and although I might be able to figure it out, after the amount of time and money spent on figuring it out, it’s actually cheaper for someone else to do it.
If you are going to buy a brand new Yetti, you can have the dealership customize it in certain ways. Or, you can have a dealership do it. I personally have not had good experience with Absolute Trailer Sales. Northland Auto Sales has gone above and beyond helping me out, so I would recommend them.
The reason I got a Yetti was not just because it is lighter and aluminum, but also because I like their standard layout, as it is more fishable. If you just want to go customized, there is cheaper options for the frame.
