The inside height highest peak is 6 feet 5 inches so if your hanging tent's height does not exceed 6 feet 5 inches then yes it will work. However, you must purchase 4 additional metal ceiling/cross poles to replace the fiber glass ceiling/cross poles. Call 1-800-681-0084.
BTW, we have purchased two of these tunnel tents. Granted the quality is not as good as OutWell tents in the UK. But, with some modification (additional guy outs#, waterproofing #silicone & mineral spirits#, structural enhancement #replacement of the ceiling fiber glass pole and adding a pvc pipe sleeve to the upright poles this tent will last for years.
