Finally discovered that my "corner leaks" were only a result of condensation... of my own making!! After hearing my heater work overtime... I determined I should add some humidity to my air. Well.... to make a long story short, this 'northerner' overdid it. And, of course, being a native New Yorker... the boiling of water for pasta dishes only served to exasperate the problem.
My apologies to all of you R-Pod'ers. And, finally?? I enjoyed my little one-person 'domain' for 3 months at Island Retreat this winter, with... 'nary a glitch'! (For a single person... *(female)... with *very limited RV experience (my late husband took care of everything) and so.. let me just congratulate myself for choosing the most trouble-free camping trailer I/He could possibly have hoped for.
