A/C Bolts that are loose, many affected

I was wondering if anyone has had any problems with water leakage coming in around the air conditioning unit in the center roof on the trailer. My husband was at an RV place the other day, not a Jayco dealer but he repairs all makes. Said he was getting a lot of the Jayco's coming in because of water damage around the ac. He stated manufacturer did not properly tighten the four bolts on the ac unit to the proper torque. When hubby checked ours they were not very tight, so far luckily no water leakage. Any way I need to know how tight the torque should be on these bolts. Any input would be greatly appreciated.

There have been accounts of leaks due to the AC bolts being too loose, in some cases "finger loose". I even made it a point to check mine one day, and they were snug. Not sure about the proper torque, I did see it one day on RVnet, but over tightening can be bad too as it may over compress the gasket. I just went by feel.

I too had finger loose bolts on both my AC units; like Crabman, I just snugged them myself "by feel".

I was told , by the dealer ,to check those bolts every year because they tend to loosen while traviling.

The four bolts on our 2011 Starcraft 175RK were not even snugged up to the frame! I downloaded the installation instructions and the newer units have yellow plastic tabs on the upper AC bracket to help you adjust the tightness of the bolts. You simply tighten down the bolt until the tab touches the roof and that will put the correct amount of compression on the foam gasket.

I always use a 4 x4 pce of luan ( real thin plywood) when doing anything on the roof, even if just my upper torso eith feet on a ladder.

Thanks all for the replies, yeh I found an article where they said the gasket is about an inch thick and they tighten the bolts until the gasket is compressed to half and inch, so hubby just tightened them snug but not overtight. I couldn't find anything on exact amount of torque, did say some of the ac units have a tab on the flat panel somewhere stating the amount of torque but could not find anything on ours. Ours is two year old and also had to replace the skylight covers, already crumbling. Hubby got all the stuff to clean roof and touch up any caulking thats getting cracked or old. You definitely have to keep on top of these things other wise end up with problems. Thank again all

By skylight covers I assume you're talking about the roof vents. When I do my spring and early fall roof inspection/cleaning I apply 303 to the roof vents and roof vent covers. Do you have roof vent covers?

JWB023: the bolts that need to be tightened can be accessed from the inside of your rig. Remove the inside cover to reveal the bolts...
