patio option

My husband and I just bought a 2012 fifth wheel fuzion toy hauler. we were afraid before we bought it that we wouldn't be able to find one with a patio option. So when we saw a new one for sale that a guy had taken out of his 2015 Raptor we jumped on it. So now we have all the spare stuff we bought-- patio fencing,table, lower bed and mattress, as well as the upper frame and mattress still in original plastic... Does anyone have an idea where is the best place to post other then ebay,craiglist that just relates to RV's tks
