Owner Banner


Our business is owned by 2 couples who have been friends since college when Ron and Jim played college summer ball together, hence, "Grand Slam Rentals". Ron and Theresa live in Bad Axe, MI where our "Chi-Chi" the Coachman Freelander is based and Dawn and Jim live in the Mt. Pleasant, MI area where our "Champ" the Winnebago Aspect is based. Ron is a Physical Education teacher and Theresa is a retired Physical Education teacher who now has fun working in a local winery. Jim is a physical therapist providing home care services and Dawn is a Speech-Language Pathologist in a local school district. We have joined forces to rent our recreational vehicles to all of you so that you can have so much fun living life to the fullest. A little bit about Ron and Theresa: My wife and I have been married for 28 years and we've always enjoyed the outdoors, camping, fishing, hiking, etc. We bought the RV, 3 years ago from a friend of ours who needed some money to buy some adjacent property next to their home and we've loved ever since we bought it. However, we also have 80 acres of our own to manage and it does cut into our camping time. My wife also works a lot of weekends, but we still love to go as much as we can. But why not share our camper and the enjoyment of the outdoors with others, when we aren't able to use it. We love to hunt, fish, camp, and golf. We have taken our RV to many tailgates, hunting trips, golf trips, and it's been an awesome experience each time. We have one daughter that is married, and has given us 3 beautiful grandchildren. A little more about Jim and Dawn: We have been married for 27 years. We have two children (Ty and Chase) who are currently pursuing their degrees in Dentistry and Optometry. We love the outdoors, hiking, gardening, planting and watching things grow, golfing and working out.

Everything was GREAT! Ron and Teresa were so helpful in getting
the RV set up and showing us how to use everything. They even had a tent they helped us set up to go over our picnic area, and they set out a rug for us. If we ever go camping in the thumb area of Michigan again, we will be giving them a call!

Ron was awesome to rent from, he went over every detail to ensure I was knowledgeable of the RV. The pickup and drop off process was seamless, Ron was very flexible with his time. I look forward to renting from Ron in the future.

The RV was an excellent condition and exactly what we needed. Dawn and Ron were exceptional to work with as well, helping to ensure a hassle free experience. Would definitely rent again next time we need an RV in Michigan.

Dawn was great to work with on our rental of her motor home. It was very comfortable and super clean! Would highly recommend!

This RV was perfect for what we were looking for. Ron and Dawn were the two members of the group we interacted with and they were both super pleasant, helpful, and easy to work with. They made the whole process really smooth. The RV is also a good one for first-timers because it drives just like a truck. We really enjoyed our camping trip, and were so glad we made the jump from tents to an RV when it rained one entire night of the trip! The RV was fully stocked with everything we needed - dish ware, cooking supplies, spices, paper products, etc. All we had to bring was ourselves and sheets/pillows. In an attempt at full disclosure, just be aware it can be a bit tight in this specific RV. It’s rated to sleep 4, and we did sleep 4 adults, but it was a bit of a squeeze and would probably fit better with 2 adults and 2 children at most.

Ron was a great guy to rent from. Communication before during and after trip was excellent. RV was in great shape and ran/drove really well. My brother and I took her through the UP for a 5 day trip with our sons and this RV made the whole trip so much easier and comfortable. The kids loved it, slept 6 easily, AC/water all worked great. This was a trip I’ll remember forever and we are really glad we rented this RV. Ron made it that much simpler and we couldn’t be more satisfied!

Our first time traveling in an RV Was very interesting. There were 7 people and the rig suited us fine. Ron and Teresa were great to work with. Unfortunately a huge truck slammed into the side mirror and had to add that to our expense. The insurance purchases with Outdoorsy didn’t cover any of it. Overall we had a nice experience with the camper and the owners as I said were great! Gail E.

The owners were super great to communicate with, the rv was exactly as described and was extremely easy to operate! I would recommend them 100 times over and over! Great experience overall!

Ron and his wife were excellent to work with.
This Motorhome was in great condition and everything was clean and working.
We loved the Interior and the bump outs provided a lot of extra space.
It was easy to drive and operate.
