Do you have a class A California license?
I've had both, pull behind and 5th wheel trailers. Both were 24 foot, none of which were toyhaulers.
I have a few friends that have Arctic Fox toyhaulers, they like them. Construction seems to be very good and well made.
The 5th wheel trailer will tow better, less sway, less hassle to couple and couple. Greater turning radius and when the hitch is installed properly will distribute weight more evenly onto your steering axle, better stopping and handling.
Receiver hitch trailers have a greater overall length, thus reducing turning radius. Requires " EZ Lift" type hitch, with weight distribution bars and the need for sway control.
Toy handlers are designed to carry more net weight and are generally heavier than conventional rv trailers.
5th wheels have a much nicer bed for adults, over the king pin area, which generally are a queen size. The benefit is not having to pull out the bed and put it away in order to get around in the trailer. The5th wheel bed does not require to be made and put away after a night's rest.
5th wheels tend to have more storage area as well.
After owning both, I'd never go back to a pull trailer!
The reason I ask about the class A license is because you can tow a additional trailer behind 5th wheel or pull type trailer as long as you don't exceed state length laws. I towed a 24ft 5th wheel with a Ford 150 and then my motorcycle trailer with 2 bike's behind my 5th wheel. I also would tow my 14ft Gregor aluminum fishing boat as well. It is legal and can be done. The reason I mention this is, "x" amount of living space is taken up by the "toy area". I know that beds fold down and the kitchen table area is now bike storage area.
To me it is a hassle. Been camping / riding with friends who had toy haulers and they seem to be always moving stuff around to eat or sleep. Just my observations. Again never owned one so I may be talking crap.
If you go to the DMV you can get info on getting a non commercial combination license. Which will allow you to tow combinations with a pickup truck.
Check out Trailer Life magazine as a guide.
Hope that helps.....
