Ontario, Canada to Indianola, Iowa

Where are you crossing?

Yes which crossing, and how long a drive to get to that crossing, what part of Ontario.
S.S.Marie and then north and west of Lake Michigan, missing Chicago
or Sarnia/Port Huron or Windsor/Detroit and go through Chicago but if your coming through Toronto, not much of a problem.

For a quick overnight stop, we avoid being close to any major city, whether it be Walmart, rest area or truck stop.

As for hookups in any rest stop, we have never seen them, some states and Ontario Enroute Centres have had dump stations and non-potable water, but many of those are being closed up.

Camping close to Indianola, check out KOA, they have several campgrounds between Chicago and Indianola

Just an FYI to anyone traveling through Ohio, overnight camping is only offered at 8 service plazas and not at the regular rest stops. These service plazas are along the Ohio Turnpike.

Oops I will be coming from just west of Toronto it is roughly 5 hour drive to border (Detroit). I thought Detroit border would be the better crossing (as opposed to Niagara area)

Thanks

I would recommend crossing at Sarnia, then taking I-69 to Lansing, Then I-69 to I-94 and west.
We have relatives in London Canada. We live in central Tennessee, so we head north and pick up I-69 in Indianapolis and use the Sarnia route.
You will accomplish two things that way. In Windsor you will have to travel a lot of city streets to get to border crossing and you avoid Detroit entirely.
