There are several different brand and style faucets used in Winnebago products travel trailers and motorhomes . While they may be from different manufacturers they all use somewhat standard mounting systems.
Here are some links to diagrams of various faucets showing their mounting systems.
Note they all use either one or two mounting posts and nuts to secure them to the counter. Those that use a single plastic nut should only be hand tightened. Those that require a socket should also only be tightened enough to hold them securely in place. Over tightening a plastic nut will either break it or strip the threads. Over tightening those that use steel nuts will damage the chrome platform that the spout and handle are attached to.

If you cant get your hand in there to tighten the nut, Lowes sells a special slotted T handle wrench that will fit up in the tight space and turn the nut. Do not over tighten.
