And make certain that tower will fold – easily — when required. Whether it's for storage, trailering, or just to squeeze under that local bridge, the ability to drop your tower is a must so don't be caught unaware or with a design that requires extensive tools and time. Today's best designs, like Roswell's Aviator or Cam RT, feature simple handles to release a portion of the tower and beefy hinges to allow it to easily fold while maintaining its structural integrity. And remember, just because the tower can fold doesn't always mean it's an easy job. Towers can weigh as much as 1,000 pounds; the best manufacturers include some means of lightening that load, such as springs, so that a tower can be lowered and raised by a single person. Roswell, in fact, holds a patent on a "weight-assist" tower design. "It makes folding the tower, making adjustments, or doing service work virtually effortless," notes the company's Ben Smith.
