If the unit is being used mostly for PSU tailgating in the PSU lots, I’d go with a MH over a 5th wheel. It’s just much easier to load it up, drive it there with friends and family enjoying the ride, and set it up and start your tailgating as quickly as possible.
However, as an overall camping machine, I’d take a 5th wheel over a MH. Once you arrive at your destination, you have a vehicle to explore with. Also, not having to deal with motor, transmission, and other problems that are typical of motorized vehicles is a big bonus.
agreed... travel-trailer for tailgating is not ideal... 97% of trailers & 5th wheels lack an onboard genset... and i recall that portable generators are verboten in the tailgating areas (though some ayyholes disregard this rule)...
IMHO much of the fun of tailgating in a MH is packing 15 friends and family in with you and enjoying the painfully slow trip into the stadium parking areas...
