Default Enjoy it!

Why not? I fly navigation rallies with my Mooney at 90 knots. It’s fun, and the slower you fly the more time you have to find the targets on the ground, or in your case to enjoy the landscape.

You RV can fly slow no problem, but your Lycoming is another issue. Assuming you will be burining 100LL, flying that slow for extended periods you will be accumulating lead build-up in the engine. You will also find that you get horrable fuel efficency.
When I fly long distances with my kids (flying a Tomahawk) I let them leave before me, and plan on passing them at the 1/2 way point. This way we are able to stay in almost constant raido contact.

Awesome insights, all. Sleeping late and leaving behind him, and then waiting for him on the ramp with coffee at the end sounds perfect.

The Carson's speed for the 8 is around 140 mph, 122 knots.

Find what your best MPG speed/power setting is, and fly that. You'll still be faster than him at that power setting, but if you let him depart first and land last, you will have a little time to help with logistics on both ends as a favor.

Really, doing that along with finding each other/joining up for a bit in the middle of each leg just for fun - I bet you won't find yourself waiting for him all that long at each stop. You'll stay entertained and fly efficiently. Plus the trip will be a great example of enjoying the getting there over just getting there.

Hopefully you're not flying in a prop 'restricted' range, most Lyc publications list 2350 as the lower limit on RPM for cruise with a 360 for what it's worth.
Most of the Hartzell prop restrictions are for 2100-2350, likely because there are more harmonics down that low.

Hi Walt, I've got the io-360 from Mattituck, pmags, FM-200, and the Hartzell 2-blade C2YR-1BFP/F74972 metal prop. I can't find any RPM restrictions, but it does feel like there are some vibrations when I go below about 2200. I thought it might just be prop balancing, which I plan to do soon. Mine feels smooth above 2200, and when I'm in "slow cruise" I'm usually at 2250. While I can't seem to find a specific RPM restriction, I am curious if there are some recommendations to avoid particular RPMs due to harmonics. It seems that this combination must be pretty-well researched, so I doubt I'm breaking much new ground with this question. Thanks for any insights.

No limitations on that prop with standard mags and compression (assuming 180hp 360), not aware if Hartzell has done any testing with dual Pmags though.

At 45% power with 2000 RPM I burn 6 GPH and indicate like 123 kts with reduced noise levels. At this lower RPM the oil temperature is actually lower despite the lower speed. My engine(s) donīt like power settings below 40%.
