I have a 13 Fuzion 301, it has a separate garage that is slightly over 10'...it fits the Pioneer...but with no bumper mods or mounted tire rack, you have to be square. The cabinet is on the front wall, none on the side. We also had to take out the bottom bunk (there are two) for the height or you could go with the fiber roof on the Honda...you have to do one or the other (remove bottom bed or the hard roof). There is some room on the side for storage like chairs, tents, etc. I also store light stuff in the buggy such as rugs, lighter chairs, table top grill, I put the rakes and shovels under the buggy. By the way you have to put the buggy in first and then load it or you could bend the ramp door (as I have
), if not reinforced. If your door has the cable kit on it from the factory to sit on it's my understanding they are heavier duty.
We love the trailer (I've had many different models over the years), had a fifth wheel, the garage was over 11' and it did have cabinets on the side and the front wall, with the dual queen beds, the buggy fit fine. But I wanted my truck bed back so I went to hitch pull again. Plus the fifth wheel 38' was a beast to pull/park in the forest dry camping.
So with that said it has: a front queen bed, couch bed in living room, 2 -slides, had 2-queen beds in the back, 2 a/c units, fuel station and on-board generator.
My friends that have the open hull toy hauler (no separate garage) with cabinets that go all the way to the back do have issues with width and have to be very careful (again very square when pulling in) none have had issues with the buggy moving but if they did it could be bad on the cabinets.
The Fuzion anchor points or D rings are welded to the frame as I understand it where others are bolted.
So measure, measure, measure before you buy. Don't get one with slides if it's open hull, it'll likely not fit or you'll have to ramp up the wheel well which they are factory built for but might rub the wall.
FWIW, It's been my experience that if the toy hauler is sided with fiberglass they have a metal frame (not all), if it's sheet metal sided it's most likely wood frame, if it matters to you. It did me.
Some of the newer toy haulers are longer in length, have longer garages and you can get them with a second bathroom.
Good luck, Mike
