What I would recommend would be to get up on a step ladder in your trailer attach a couple of these to the ceiling then put a hook in each of your eyes and jump off your step ladder.
this is close to what i use... I have the big ones for blinds, and 6 in ones for bags,, just bought 6 more for 20 bucks a couple weeks ago... can't find the site right now though... they hook into surface mounted "rope/D" hooks ... simple method..... http://shop.easternmarine.com/index.cfm?fuseaction=catalog.prodInfo&productID=9058&categoryID=235
you can get those at you local menards...
