After a trip back from Tahoe I notice some white residue trailing back from the top forward corners of mf rear doors. Upon further examination I noticed the forward corners of the rear doors have rubbing against the top rear corners of the front doors. Enough to wear it to bare metal. There is adequate gap when the truck is not moving but I have yet to find a volunteer to hang on to the outside on bumpy roads. Anyone else notice this? It goes in tomorrow (today) for a few other things. We'll see what 5 star has to say.
