I don't have any experience with Forest River or any toy hauler for that matter. But I've been shopping around to get one myself. For the past few years, I've been using my dad's Jayco Eagle TT with my family of 5, which is actually a great camper, but is not a toy hauler obviously. So we've had the benefit of seeing what we like and what we don't like about it and finding what we would want in our own camper/toy hauler.
I saw on your other thread that you would like to be able to haul at least 3, maybe 4 ATV's. The nice thing about the Vengeance line is that they are 102" wide, so you should be able to get 2 ATV's side by side. Plus since the 25V isn't a "garage" model, you can put at least a 3rd ATV up into the kitchen area. Then, being a travel trailer, you could probably haul a 4th ATV in the bed of your truck. So it should suit your hauling needs.
On the down side, and this is just personal preference, but having to walk thru the bathroom to get to the main bedroom is kind of awkward. Plus, I don't know what you will need in terms of sleeping arrangements and numbers of people. But it looks like the kitchen is very small with no counter space and minimum storage. But I've found most toy haulers often trade storage space for hauling space. So you would need to look and see if this suits your needs. If you are camping by yourself most of the time, then you probably don't need much storage space. But for me with a wife and 3 kids, I need all the storage space I can find. I hate tripping all over a bunch of stuff piled on the floor because there are no cabinets to put it out of the way.
