I recently purchased a Frabill Adventurer and want to convert it to the stadium or boat style seating system (has two camp chairs not so comfy) similar to the ones on the Trekker. When I contacted Frabill they said unable to do so as there is a support bar on the Trekker that is needed for support and structure of the seats. If any one could send a picture of the underside front of their Trekker so I may fashion home made support it would greatly be appreciated .
