Struts that hold engine compartment door open ??

Here's the info off the tag on the strut. AVM highway 76 East Marion SC 29571 1-800232-4AVM SE350V120AL 2963
Do Not open....High Pressure.
I called that number but got a recording offering a free Caribbean Cruise, no mention of sturts.
The last numbers are 120 I'm sure if they were rated at a 120lbs it would keep the door up, so I have my doubts if that's a rating. This is on a 2004 Fleetwood Revolution 38B.

Just did some searching and found the company, will give them a call tomorrow, thanks.
