My 27WP TH came with one set of stabilizers only - I can't remember front or back. My dealer GAVE me a pair for the other end but he was very adamant that I not call them "jacks" - they are stabilizers only not to be used for lifting the camper, only to keep it from rocking when you walk in it. I guess FR figured you'd never un hook or that the tongue jack (yes that is a jack) would hold it stable. The stabilizers were easy to install. Drill 4 holes for each in the frame, put in a good grade 5 bolt and use a nylon locknut and it's done. My camper is very stable now that I have a stabilizer on each corner.
