Normally I would opt for a 5er, but if the golf cart would fit in the truck I would likely go for the non toy hauler TT. A toy hauler, while nice for carrying your toys, you do lose a lot of normal living space. The kitchen/living area size is reduced for the garage area, although some do make good use of the garage for some living space. Many tow a small utility trailer behind a 5er for their toys, but you might get into states that do not allow the extra trailer especially along each coast.
With a 5er you will need to make sure your truck has adequate payload rating for the pin weight.
