@100Acre I think the main regional difference I have seen in toy haulers is the garage style is favored on the east coast and the open style on the west.
I have an older 24' Weekend Warrior with an open floor plan.
Picture shows it full, Pilot, Odyssey and 2 ATVs.
The disadvantage of the open style is you get mud everywhere after riding and you are living on top of the equipment.
If you are doing a long trip this could be a pain.
The advantage is you can keep stuffing more junk in there.
Living in SoCal where I am from the riding area is a long days drive away.
So this type of set up makes sense, you cram the box full of toys, then when you get there you dump it all out and have a larger usable living space.
With the experience I have had, to me the biggest issue is what materials are used in construction.
My toy hauler was new in 98, so it is over the hill.
If I ever replace it with another trailer I'm looking at all aluminum construction.
If the box dose develop a leak - and it will - you have some time to get it fixed without inuring more damage.
Definitely stay away from a chip board floor or roof (WW has both).
Also, thanks for the grand tour of your 4wheel camper at the take over.
I really like the concept and execution of there slide in's.
Growing up Dad had a home made tent trailer that he hauled all over behind his Jeep Wagoneer.
But it turns out my wife is not sold on the soft sides.
By finding this out now you have saved me a lot of sleeping on the couch.
