We have a new to us 2002 Winnebago Adventurer. It will usually start, but it turns over more slowly than it should. After driving a hundred miles or so, it will not even turn over until it cools down for about 30 minutes. I suspect the brushes in the starter are bad, but I’m hoping for some added insight. My battery shows 12.6 volts.

12.6V is on the low side. A load test would be useful. Does jumping or using a boost charger on it help speed up the cranking?

I have a battery boost that will connect my house batteries with the engine battery but it doesn’t help. I’ve also tried jumper cables.

Usually when boosting doesn’t help, it’s the starter or cables.

I’ve pretty much checked the cables. I think I’m going to pull the starter relay and use a jumper wire to bypass everything. I think that will tell me if it’s the starter or something back up the line. I had thought it might be the remote relay, but I believe they usually just make a single click sound if they’re bad

I have experienced a starter on an older vehicle which bound up when hot due to worn bearings. It worked fine when cold. Just another possibility.

On a 2002, I’d want a new starter regardless of the problem.

Is it a Chevy/Workhorse chassis? If so, it is probably the starter. They are notorious for cranking slow when they get hot. Replace the starter with the best starter you can find regardless of price(that's what I did) and no more problems with hot start.
If it's a Ford, I don't know if they had the same problem.

Sometimes a starter can fail in such a way that even the jumper batteries can be depleted in short order. Best to replace the starter motor after double checking the condition of your batteries under a load test. That is the right way to test them.
