Look at those flimsy non mortise hinges. Four screws total. One screw each in the end flaps which in turn twists it when tughtening, causing a bind on the pin and then squeals. Lube away and the squeals MAY
stop for a few swings
You may have more clearance between the frame then our 5ers doors and can use replacements from either Lowe's (Gatehouse brand) or Home Depot (Primeline). If a good carpenter, you could alternatively take the doors off and use mortise type hinges. Or piano hinges which I have considered.
I'm trying the Gatehouse brand in the next few days but am not upbeat since the HD Primelines were too thick. If all else fails, I'll open the clearance with a run through my table saw which of course means I'll need to do some staining too.
Ain't life fun with an RV? Always something nagging to work on
