Eric,
thank you for the info. Much appreciated. I'll be working on the trim pc later this week, (i want to beat the winter rains). I'll also try your advice on removing the storage doors, (a sort of practice run for the future). As for the vertical band where wall meets endcap, i'm guilty of sealing the band to the wall at the rear corners but will do as you suggested (again, hopefully before the rains). I did the roof bands (front and rear) 2 yrs ago, the rear has sprung a leak so I plan to redo them both. The band at the drivers window has been resealed, but at the entry door i have a mysterious leak. somehow water enters above the door frame and (mostly, though not always) when that corner is low. Still scratching my head on that one. although gettin closer to solution.
Again, thank you Eric, Lots of good info.
Peace, health and safe travels,
Serge
