my 79 argosy's door closes just fine from the outside, just a gentle knug engages the door closed. from the inside however, i cannot pull in the door hard enough to get that "click". i'm pulling on the screen door handle, but it won't be long until that fails, and i'm running out of superglue to fix the interior latch that keeps breaking from my attempts to pull the door closed. then the other night i used the pliers to pull the door closed, and "voila" locked inside. i had to get someones attention to open the door from the outside. at first i thought maybe it was a leveling question, as i've seen that posted widely as the culprit, but the fact that the door closes fine from the outside, makes me think it's something else. any suggestions would be appreciated
