Timely question for us. We are just now setting up our Jeep as a toad after seeing ourselves with a medical emergency about 30 miles from the closest ER. Granted, we've had the Class C for a year and never needed a second vehicle before.
That all said, there are lots of ways to camp without a toad. A recent example: we camped at Mackinaw City in Northern Michigan at a campground that had a shuttle to the docks so we could take a ferry to Mackinac Island.
We also like to get lake front sites so we can enjoy our campground without having to travel anywhere else.
That's about to change with having the Jeep and I'm secretly thrilled because I love, love, love sightseeing. DH doesn't as much.
Whatever you decide, you can always adapt and make changes.
Happy camping!
