OK junk may have been the wrong word however without getting into custom builds,toy haulers have a lot of great features but they are not as luxurious as a luxury 5th wheel.
Some are taking the OP's comments personally vs. grasping the OP's point.
On the other hand I'm not sure why the OP is seeking out tow haulers if they are truly looking for a luxurious fiver.
There are 2 different types of RV's designed for two different markets.
In the end one is not necessarily better than the other, they are designed for different use.
Toy haulers have grown in popularity due to their space and versatility. Some models do have lots of luxurious features nevertheless a typical toy hauler does not have the same amenities and features as a high end 5'er.
