Most the the pros and cons are listed. Everyone has their own use, we use ours even when not bringing toys, but we are almost never in our trailer. So the inside layout isn't as important to me. The wifey however.... She wanted more room than the bumper pull, so we just upgraded to as fifth wheel, which I would recommend. Our new fifth wheel that's 9,800 dry gets almost the same mileage as my 23 foot bumper pull at 5,200 dry. I'd look at the 33 models of the forest River Shockwave/sandstorm/stealth. Or eclipse attitude 32 model. They all have 3 Queens beds and a fourth twin bed for friends or whatever. And they have 2 bumpouts.
I do agree on going toy hauler route. They are heavier and more expensive but they offer more features. Even if I got rid of my quads, I'd still own a toy hauler because the versatility, it's so easy to drop the ramp and load everything.
