There are a lot of folks that do both I would guess. It depends on how comfortable you are maneuvering a long trailer in and out of campsites, and if the ones you want to frequent have sites capable of taking it. Checking websites or calling on the phone would be a good idea before you go there. We have a few state parks that have short sites that it wouldn't fit into, and many that limit to 40'. That trailer lists 37'8" as total length.
That model sure would give you a lot of living space. Maybe someone else will chime in with some thoughts. BTW our TT is only 23', so I can't comment from personal experience on towing one that size.
If you're going to "regret it in the morning", sleep until noon.
