Well, I don't have too much to add yet as it is just now starting to look like spring around here. :-) But we did take it out once last year before we put it away for the winter and are going to take it out this upcoming weekend for a short trip.
The trip last year went fantastic, no complaints at all. Everything worked perfectly, was warm, comfy, cozy on a cold fall weekend.
We kept it outside this winter and unfortunately, never were able to get the cover we purchased put on. It snowed before we got over there to put it on and since then, it has been wet or snowy weather every other time we had a day to go over there. However, my boyfriend checks on it a few times a month and it is doing fine - dry inside, no leaks anywhere.
I cannot comment on storage really either as, like I said, we have only used it once and didn't pack it full of all our stuff right before the winter. I know I have plans on where I will put everything and I don't foresee any issues.
We went to a few RV shows over the winter and looked again at small hybrids, including the smaller 147X, and we still stand behind our decision to get this one - the floor plan just makes sense for us - 2 adults and a large dog.
Towing - now I don't drive it, my boyfriend does - but we have towed it without a hitch distribution kit or sway bars, with a Chevrolet Silverado 1500, about 300-350 miles so far, with no problems. One of the main reasons we picked this size and style camper is due to the light weight and ease of towing as we like to go for short weekend trips and/or move around from campground to campground during longer trips and didn't want something that was difficult to grab and go.
One more thing - we did find a few issues with the camper when we did out initial walk through. And although we did have to follow up pretty aggressively with the dealer to get resolution, the warranty department at Forest River, came through on their end. In fact, we found a small tear in one of the mattress covers on the bottom and requested a new mattress cover. They sent us a brand new mattress instead, along with the other replacement parts we had mentioned. (We had them sent to us instead of to the dealer as we live a few hours from the dealer and will just do the repairs ourselves.)
So - that is all I have for now...I can tell you more after this weekend's trip.
