They don't affect maneuverability all that much when compared to a standard travel trailer. However, you get a lot more living space in the same effective length due to the portion between your pin and rear truck bumper being now livable space. They do however TOW quite a bit better than a travel trailer as far as comfort. Going from a 28ft TT to a 40ft Toy Hauler yielded a lot better towing/reduction in driver fatigue over long trips (also went from a half-ton truck to 1-ton, so some differences just there as well).
