We have a 2020 382WB-R which came with the Furrion and would like to have it replaced with the Insignia NS-RNG24SS9. Has anyone out there done this. GD was adamant that since it didn’t come with our model year, they would not accept it back if it did not fit. I realize with the difference in size/configuration, some changes will need to be made to the counter. Our friends have the same GD model but a year newer, i.e. 2021, which came with the Insignia. Our dealer is willing to provide the labor to install.
