2022 Jayco Precept 36C. I have fully upgraded the suspension and solar System! Total of $8,000 put into the chassis so it rides smoother and is much quieter on the road. There are a total of 4 Deep Cell 6 volt batteries that are charged with a total of 600 watts of solar. We don't have to haul around the in-laws with us on trips anymore so, we are down sizing. Please let me know if you have any questions. Thank you!
