According to the good folks at Alpha Foxtrot design, "Our rack has an option for using flat panels on the top of the rack to create a flat space that is 86”x47”   So, yes!   Add a few accessory panels evenly spaced for support.  And/or, add a few extra cross bars with gaps no wider than 8".    (NOTE:  When purchasing a Rev Rack Tent be sure to choose the mounting option "other" on check out.)  If you mount your Rev Tent to a Alpha Foxtrot Rack, please share a pic with us so we can include it in this article!
