But full frame has other advantages besides blurred backgrounds. If I'm serious about my little photography hobby, shouldn't I want a full frame? Advantages I read about are:

• Dynamic range
• Low light performance
• Shallow DOF
• Detail and resolution
• Wider field of view

I just looked and the RP full frame is back in stock in refurbished for $549.

The available list changes daily. They are sales demos, returned stock from closed stores, warranty repairs etc.
The RP full frame just went back in stock today for $549 refurb. Simple controls but small and takes great pictures.

Yes, you will need a EF2R adapter for the R10 to use your current lens. You will need an adapter for any of the mirrorless cameras if you plan on using your EF/EF-S lens on the mirrorless body. You can get one as cheap as $35 or so and up. The one I got for mine cost $135.00 and has drop-in filters. Pretty handy if you ask me. Yes the R10 is a good step up for the 60D. I moved from the 70D to it.

my solution is own both FF and Crop sensor. My two new R series are the RP (I don't do a lot of FF but prefer it for macro and landscape) and an R7 the R line version of the 7DII wildlife/action camera.

If you are patient and shop the refurb site you can get a FF and a Crop sensor body for about 1 1/2x the price of one of them new in box. Their refurbished lenses are just as great a deal. Many prefer the refurbs direct from Canon since the going over, tuning and inspection they get is actually more extensive than the new ones coming down the assembly line. And then they add on the same warranty as new in box.

I tend to buy full frame lenses since they work on both bodies. The crop sensor lenses I have were bought for one reason - small and light (also lower cost) for carrying out and about.
I may not have to do that on future purchases as I just got an electric, street legal (lights for night also), mobility scooter with cargo box and a 40 to 50 mile range which will get me to, ride around taking pictures and back home from my 3 favorite parks, nature trails for photography. It is rated for 25mph but yesterday I got it to 50 kph (31mph) on a flat street so the furtherest of my favorite parks = 10 miles away. 1/2 hour each way with traffic, lights etc, 10-15 miles of running around and home with a safety margin of 10+ miles still on the battery.

Excellent, thank you. Love "vastly improved AF, tracking ability and eye detect."

I'm liking the refurbished idea. I could get a better body than I would if I bought new. And I can be patient for the model I want. So looking at the refurbished mirrorless bodies, do you think that the EOS R6 would be the way to go?

Would I need an adaptor for the R6? Can someone provide a link(s) to recommended adaptors? I don't mind spending a few extra bucks for better quality and drop in filters.

Yes all the R bodies need an adaptor to use EF lenses, the adaptors allow EF-s lenses to go on either the FF or crop sensor R bodies.

here is a rundown on the adaptor's made by Canon and a couple third party models:

Keep in mind that using a lens designed for crop bodies on a full frame sacrifices an inordinate number of pixels. You wind up using ~39% of full frame sensor pixels.

I went from an 80D to the R7 and am happy as can be with the choice. The R7 is an APS-C body with IBIS (In-Body-Image-Stabilization) and awesome focusing features like auto eye focus. I can use all my EF and EF-S lenses with no pixel loss with an EF->RF adapter.

I didn't realize lenses were designed for FF or crop. Are both my lenses (Canon EF 100-400mm f/4.5-5.6L IS II USM, and Tamron 16-300) designed for crop sensors? Is this an argument for not buying a FF body?

Look here, this company makes adaptors for other mounts and brands of lenses to work on Canon R bodies:

Also lens reversing mounts, extension tubes etc.

Any DSLR????? Even an IBIS enabled DSLR? Why would that be? Please don’t confuse the difference between DSLR and MILC with the difference between {discontinued} DSLR without IBIS and {new} MILC with IBIS.

The 100-400 is an EF lens, designed for full frame or APS-C (crop), but the 18-300 is a crop body design. The image it casts does not fully cover a full frame sensor at all focal lengths. I'm not sure if a Canon full frame R series camera would switch modes on it. I would mind the significant loss of pixels on an RF full frame camera (or any modern mirrorless) when it goes into crop mode. That is why I went with the R7.

Like new worth the price

If it fits into your budget, an R6 is an excellent choice, and since the R6 MK2 is being announced, there may be good deals on R6s, especially refurbs from Canon. Your 100-400, which is a FF lens, will work fine with any of the Canon RF to RF adapters, and you may find a bundle on an R6 that includes it. Your other lens is a crop lens, and if you’re going full frame, your best decision is to sell/trade it for a FF lens.

Your crop choices are the R10 or R7. If it fits into your budget, the R7 has image stabilization, which the R10 doesn’t and in my personal opinion, that’s half the reason to go mirrorless (even though your 100-400 has IS)

Regarding FF vs crop, your observations about the advantages of FF are spot on. There are only 3 reasons to consider a crop body as an upgrade: (1) if you shoot birds or other wildlife at long distances, the 1.5 “crop factor” gives your 100-400 the equivalent field of view as a 150-600 on a FF. (2) IF and only IF you buy crop lenses the combination is smaller and lighter than FF. If you keep and use the 100-400 or other FF lenses, the difference in the total package is minimal. (3) crop lenses, in addition to being smaller and lighter, tend to be less expensive, BUT there is a larger selection of FF lenses in the Canon lineup and all the specialty lenses (such as tilt/shift) and high performance lenses (such as your 100-400 and “L” series are FF. If you’re going to use FF lenses, you might as well get the advantages of a FF body unless you need the “crop factor” for additional “reach”.
