OP here with an update...
After a couple more trips followed by the Bug slide method outlined earlier in this post I am happy to report that it just keeps getting easier. Now just a blast from the hose and couple of light passes with the long handled brush and car wash soap gets about 95 percent of the bugs off. I still use the 6' step ladder and a little Bug Slide lightly buffed with a micro fiber cloth but each time it leaves an even better, virtually non stick surface/shine.
I recently started using one of the new high tech polymer sealant polishes I found on the internet "Torque Mirror Shine" {Google it - available on Amazon} on my 2019 Honda Ridgeline and my 2017 Indian Springfield with awesome results. The key is get the vehicle extremely clean right down to the clear coat before applying the polish. This is best accomplished using a clay bar treatment {I like the Mothers Clay Bar kit consisting of their liquid detailer which acts as a lubricant for the clay bar - comes with 2 bars}.
After having such good luck with the Honda and the bike I did the front of the Class C :
Keep in mind this is a 2012 coach, not too shabby for 9 years old... :B
The polish is about the color and consistency of milk and just wipes on easily. Just lightly wipe it on and then buff it out with a dry micro fiber cloth and voila! It is supposed to last 6 months with just a couple of coats applied. I did the Honda from start {washing, clay barring and 2 coats of the polish} to finish in under 2 hours.
