The 2-valve V10 doesn't make that much more power at higher RPMs, yet the noise level is much louder. I prefer to limit engine speed to around 3,500 RPMs when not in a hurry which balances performance versus noise to my liking.
"Damage" is a strong word, but there is no doubt an engine pushed hard will wear out faster. Fortunately, most motorhomes don't get driven enough to wear out a V10. Mine is at 167,000 miles, but only has to move a small and light van, so it's had an easy life. So far no major repairs -- just a recent water pump due to related coolant leak.
Even when driving larger (rented) motorhomes with V10, I ease up on throttle to keep engine RPMs to no more than 4,000. I just don't like that much noise.
P.S. -- The 2-valve V10 makes 85% of power at 3,250 RPMs.
