Recently, my screen door push lock/opener broke (small pin inside actually broke), ordered a replacement door opener complete from Sullivan RV, $20 including shipping, just replaced the pin and keeping the rest of the assembly as spare parts. (never found the pin for sale by itself)
Soon after, I ordered a wardrobe door frame from Fleetwood (mine was cracked when I bought it from swinging open during travel, I presume), frame was in stock and arrived quickly, but was broken in the box, no visible damage to the box.
Now Fleetwood wanted pictures (which I took and emailed them), and now they are replacing it but no more in stock, so they say a week and I'll have it, cost $70.00, and I just checked my CC info online...$30 added for shipping...STEEP, especially when it arrives broken...
