As we all know, the 29M's cargo doors do not have gas struts installed to keep them from flapping in the breeze so I installed my own this weekend on every cargo door with a slam latch plus the LP compartment door for a total of 6 doors.
The following parts were purchased from
Camper Parts, Camper Supplies, RV Parts, RV Supplies: RVupgradestore
20-1110 JR Products GSNI-5300-10 Gas Spring 20" length 10 Lb force (6)
20-1071 JR Products BR-12552 Gas Spring Angled Out Mounting Bracket (6)
20-1072 JR Products BR-12695 Gas Spring Raised Mounting Bracket (6)
I also used 6 4"X4" stainless steel plates as backing on the doors. I happened to have some on hand but you can get them at any hardware store. The Raised brackets were installed approx 20" from the door hinge in the compartment. The steel plates were glued on the door approx 4" from the door hinge. The Angled Out brackets are screwed into the plates. I also used #10X1" self tapping screws for the raised brackets and #10X5/8" self tapping screws for the angled out brackets.
That about does it. If you have questions, just ask. Pictures attached.
