Our first toy hauler was a Weekend Warrior FS2600 bumper pull. When the last of our kids/helpers moved away, we decided we wanted more comforts and less work, so we upgraded to a fifth wheel with a dedicated garage, auto-levelers, and big slides. Best decision we could have made. It's a totally different experience.
There are definitely pros and cons though.
We boondock a lot and we can get into most of the same places with the big fiver as we did with the shorter bumper pull. The fifth wheel is easier to maneuver, but the TT had a little better ground clearance. It's a toss-up as far as boondocking goes.
In actual camps though, it takes a lot more planning to secure a space long enough for a longer fifth wheel. We can't get into any State/Fed campgrounds. We camp at a lot of County places though. Even though the spaces aren't much bigger, they don't have the same staffing and it's pretty easy to get creative and shoehorn into a space when there isn't any supervision (a victimless crime). In private CGs / RV Parks, we usually do pretty well finding a space. Sometimes we have to compromise and dry camp in the overflow, but that's pretty rare. Those longer spaces definitely come at a premium though. We have to be careful on longer trips, because the longer spaces at the private RV parks can really add up.
So yeah, a bigger triple-axle fifth wheel toy hauler will make you work a little harder to find a spot and it will cost a little extra. We've never regretted the upgrade though. The experience with this more comfortable hauler has been fantastic. We've done a ton of camping in it in the past six years, including an 11,000 mile trip. Our older/smaller Warrior was just too primitive for extended trips like that.
