925 or 845 would work for you in that case as they are a good 6 Month Wax used alone not to mention how long that extension could be with the occasional spray wax.
I have not tried the Mckee's but referring to the statement with the trailer. I have a 32' 5th wheel with approx. 960 sq. ft. of fiberglass. I have Collinite as a base and use Optimum Wash and Wax as a rinseless and QD (because of the added Car Wax in this product). Then at no longer than 3 Months I add a coat of Optimum Car Wax and repeat every 3 Months or so. I have had to Rotary/Compound this beast several times over the years until finally coming up with this regiment. Granted, there are still times I have to break out the Collinite 870 but that is still a whole lot better than the rotary, wool pad, compound and the endless hours of work.

Dave would Hydro Blue be a good solution for your large 5th wheel?

Scott, not really sure and have not really looked into it. If I remember right (rarely happens anymore) the longevity is not very long but it went on with the wash ?. I will have to take a look at it.
