EDIT: Shoot, just saw you mentioned you're after toy haulers. You may want to ask this question in the toy hauler forum as well. We were plenty happy with our Keystone Impact toy hauler... it was just big. Most toy haulers are unless you want your toys stored next to your kitchen (aka no separate garage). Keep in mind that your living space isn't that much bigger than a truck camper unless you buy a really big trailer, since most of it is taken up by garage.
We did a lot of research when we purchased our current rig. We downsized from a Keystone Impact toy hauler.
My first suggestion is to figure out a floor plan you like. I found that pretty much every manufacturer makes almost the same exact floor plan. Some are even the exact same, but different lengths, so just more space between "things". I narrowed ours down to Grand Design Reflection and the Keystone Montana High Country as both had a floor plan we liked along with the size we wanted (under 35') I really liked the Grand Designs but they did not offer a Gen Prep option which was a deal killer for us.
I did look at Arctic Fox at an RV show as their boondocking capabilities were appealing and it felt dated and had the exact same floor plan as my in laws 1998 5th wheel down to the shower opening directly next to the bed. No thanks.
