New 248BH owner..leak proofing

[exjay]

Just got a new 248BH Amerilite Friendship. Previously owned a Jayco Jayfeather 165 and learned about leaks and lack of maintenace on a camper from the PO and dealing with the results/repairs. Anyways, first thing I did after bringing the 248 home was re-Dicore everything on the roof, re-silicone any questionable areas on the siding ends/joints, around all lights and bottom screw heads on botom siding panels, apply spray on undercoating the wheelwells, sprayfoam seal all floor openings for pipes/wires, apply light coat of undercoating on tarp type enclosure underneigth and under diamond plating where it meets the floor to help with vehicle spray, and tighten all drains under sinks/tub (found less that hand tight), the windows look pretty well sealed but do need to snug up the storage doors some for a tighter fit. Anything else I may want to check/seal up? Doing a mini camp inthe driveway soon to really check everything over before storing for the winter. Thanks.
