I recently did research here, and started a thread on this topic. Here is what I tried and what is working well for me.
My camper is an '09 Grand Junction FW with fiberglass exterior.
On our last trip, we arrived home after dark, so the exterior went from needing cleaned and waxed, to a front cap that was desperate for attention. It was covered with road grime and bugs. Other parts of the RV were only a bit dull from oxidation to roof water stains, on both the paint and decals. Products used were Formula 409, Paper Towels, Magic Eraser, and Meguiar's Cleaner Wax.
On the front cap, I sprayed 409 over an area, then rubbed / wiped off the 409 with paper towels, which removed the road grime, and some of the bugs. More rubbing with the wet paper towel got about 90% of the bug grime. A second pass with 409 and clean paper towels was needed to remove all of the dirt loosened by the first pass.
Alternate: I sprayed 409 over an area, then rubbed / wiped off with Magic Eraser, which removed the road grime, and 95% of the bugs. More rubbing with the Magic Eraser got about 99% of the bug grime. A second pass with 409 and clean paper towels was needed to remove all of the dirt loosened by the first pass.
With either method, once the entire cap was clean, I applied the Meguiar's Cleaner Wax with a white wash cloth per label directions, allowed to dry, and wiped off the haze with a clean towel.
On the sides, the issue was some road grime and lots of oxidation, and white roof stains on the decals. I also had a few spots where the oxidation had been "wiped off" by "attack trees" on our first outing. This made a good area to test oxidation removal.
I found the 409 did an excellent job of removing dirt, water stains and oxidation with simple spray on and wipe off techniques. Often, no second pass with 409 was needed. This left a clean surface with minimal dirt to be removed by the cleaner polish.
I also tried the Meguiar's Cleaner Wax only on similar areas. It did an equally good job of both cleaning and oxidation removal, but it took a bit more rubbing and the applicator cloth, which was picking up all the dirt, needed much more frequent replacement with a clean cloth.
IN SUMMARY
Formula 409 did a great job of cleaning general dirt, road grime, white water stains and a bug removal. For most areas, paper towels work well for this cleaning. In areas with more grime or bugs, Magic Eraser improved the cleaning significantly.
For most of the camper, only one 409 application was necessary. Particularly dirty areas required a second application to remove all of the dirt loosened up by the first application.
Formula 409 only did a fair job of hard water stains below the water heater.

Meguiar's Cleaner Wax did a good job of cleaning general dirt, water stains and oxidation. It required more rubbing than the 409, and required frequent clean cloths. It was NOT tested on the bug covered front cap without prior cleaning.
Meguiar's Cleaner Wax clearly left a sheen on the front cap, and it is MUCH smoother (wipe a cloth across the surface before and after) than untreated. It was more of a semi gloss than a high gloss. I have no idea when it was last waxed. I am happy with the results.
