The Great Outdoors

When you rent a camper rental in Janesville, you will want to get out and explore all that nature has to offer in the area. Just north of the city is Lake Koshkonong, a lake that is over 10,000 acres large and is a good place to boat, swim, and fish. The lake has a few public boat landings, and fishermen are able to catch Panfish, Largemouth and Smallmouth Bass, Northern Pike, Catfish, and even Walleye from the waters.

RV Parks

When you book a camper rental in Janesville, you will probably need a location to park for the night. While the majority of RV parks in close proximity to the city are located to the north, up near Lake Koshkonong, there are a handful of RV parks that surround the lake, so it shouldn’t be hard to find a place to stay a night or three while you enjoy your Janesville RV rental.

Exploring the City

What Janesville may lack in big city draw it makes up for with small city charm, and the Rotary Botanical Gardens are one of the many beautiful attractions that Janesville has. These award-winning gardens encompass over 20 acres of land, throughout which there are 24 different garden styles with approximately 4,000 varieties of diverse plants. Visitors to the gardens can explore on their own at their own leisure, or sign up for a garden tour and have all their questions answered.

Our first road trip was a success! Thanks to G&G for renting out your van for others to enjoy and for being incredible hosts. The quick response when we ran into a hiccup was very much appreciated. The van ran smoothly and not a complaint about discomfort from the anyone. We drove from Wisconsin to Connecticut and it felt like we only drove for a few hours. Five stars from this group!

I was initially worried given the age of the vehicle, but Dave was very good at keeping open lines of communication and doing what he could to keep my trip easy and comfortable. Though ultimately this RV was a little small for my specific needs, we still had a good weekend and didn't have to worry about much of anything. I sincerely hope that should Dave continue offering this unit for rentals that people don't let the other review dissuade them. It stays warm in cold weather, the fridge and freezer work excellently, and the RV works as expected overall.
Thank you again!

⭐⭐⭐⭐⭐
Perfect for Our Epic Cross-Country Adventure
We rented this trailer for an incredible journey from Wisconsin to the Redwoods, with stops at Theodore Roosevelt National Park, Portland, and the Columbia River Gorge. The trailer performed flawlessly through every mile and terrain change. No mechanical issues whatsoever, even hauling through mountain passes and winding coastal roads. Plenty of space for our gear and comfortable for the long haul. Made our Pacific Northwest adventure stress-free and memorable. Highly recommend for long-distance trips!
