Spent the day underneath my 2018 Imagine 2400BH adding a custom bumper (with 2in receiver) to find some less than satisfactory workmanship. I have no idea how I have not had more issues after seeing how the water lines are not insulated at all. I cut the PEX and moved to the hole in the cross member next to the heater duct and added 2in insulation board between the plastic underbelly and water lines. Some of the stuff Ive seen on this thing.....
