if you want a 'cleaner' installation and have electric power at rear of RV where the ladder is, i'd get the RV spring-base omni antenna and mount it on ladder.
to make it a clean install, i'd remove one of the ladder 'stays' (horizontal bar that holds ladder off the back of RV) and drill a hole such that the stay covers the hole. then i'd drill a hole into bottom of the stay and run antenna cable through the stay, into the back of RV, ultimately attaching to the rf/antenna jack on your USB760. the advantage of doing this is if you decide to remove the antenna to sell the RV, there won't be a visible hole in rear of RV. you can try antenna alone at first, and if you decide you want to add an amp, you'll just mount that inline, inside the rv, between antenna lead and adapter cable that makes connection to USB760.
operating the CTR500 from back of RV will still give you more than enough WiFi range... the only other issue you might have is adding WiFi to the desktop if it doesn't already have it.
