Tow or not to Tow

In 5 years of summer trips, we towed 1 year and it took work to get to it and turn around with it. But your case is the opposite: you're used to it. I'd suggest you bring it for storage, flexibility in a breakdown, and because you're used to having it when needed. It won't annoy you because you're used to driving it, so just keep with your normal usage. I don't see a reason to change what's been proven to work for you, regardless of how the trip may be different.

I think you could pretty reasonably get by without a towed vehicle on the trip, but also there probably are times where you could make good use of one if you had it. Its presence or absence might tend to alter what you end up doing--and it sounds like a fabulous trip in any case.

I find that, for me, there's little reason to bring a towed vehicle. I do sometimes carry a bicycle, and sometimes have to get a little exercise walking from where I can park or camp to where I want to be. I also at times make use of public transit. That said, parking at places that are outside of large cities is not usually a big problem, particularly if you're willing to park at a slightly remote spot, and stopping for groceries or other supplies en route is not at all tricky to manage when you're moving from one destination to another every few days or oftener. Camping at one location (particularly one not served by other transit) for a week or two or three is somewhat of a different matter.

That said, there's no doubt that there are occasional limitations to not having a towed car, and I'm sure I choose trips and destinations where it's not a problem while I may do otherwise if I travelled with one. Similarly, there are probably a few places I've gone or things I've done or places I've gotten fuel that I would avoid if I had a car towed behind. There are also a few trips I've made in a car that I would be less likely to do with the motorhome.

`We can go sight-seeing in our 28 ft C. Only issue is making sure nobody takes our spot at the campground while we are away. (They don't mark them as occupied like they are supposed to here) We leave stuff in the site we can afford to be gone when we get back! :( .

On a trip like you are planning, one thing might be if the C broke down and had to go into a garage for a couple of days, you would still have wheels with a toad.

I might take the car as a lifeboat, in case your motorhome runs into any mechanical problems. Some stretches of highway out that way are unserviced and if you broke down, it would be nice to be able to go for help if you needed to. Cell phone coverage is not always a sure thing out there. If you stay on the interstates as much as possible, you'd probably be OK without the towed.
