I'm very glad to find you here,I tried to join the aframe group on facebook to view your article two months ago and still waiting for a reply. Yes please,I would like to see all your info. Like to add the gas springs to my 2013 t12rb. thank you
Here is the Article on Adding Gas Springs to an A-Frame Trailer
Here is the article. If you need considerable uplift help I think it best to use longer springs than I did and keep the force down to 20, 30 or 40 pound springs. They are reportedly 25% above that when compressed.
I could have been happy with 4 each 30 pound springs but only trial and error will tell you what works best. The greater the force the more effort required to close the trailer. These springs keep pushing all the way up and don't give out as do the huge original springs at the end of their travel.
This is a new concept and you will need to take some risks as is the case for trying anything new. I was willing to do this because replacing the giant internal springs is not something I would choose to do every 5 years when I could swap these out in less than 5 minutes and for a lot less money!
Thank you so much for all your information. Sorry for my delay in replying. One more question,Flagstaff suggested two struts on the side opposite the door, your info seems to suggest four struts, four does sound better. Couple of photos attached, its a Flagstaff Classic,similar to an Aliner, and our camping dog. Thanks again.
I had to start from scratch without any help from anyone. I hope my findings and the original article from the concept founder in Australia put you further ahead.
Using more gas springs means lower force springs can be used with each one. When compressed I understand the force goes up 25%. The indicated force is apparently at the end of the travel. I would go with four each 30 pound springs in mine if it wasn't for the refrigerator in the way of the 4th.
If your roof is getting really heavy to lift I would likely recommend using longer springs to get a bigger moment arm instead of higher force springs. This would also place the load closer to where the internal springs originally provided sufficient force to lift the roof panels.
The only concern I have heard about is the impact of the upper pivot ball to the roof panel area with high force gas springs. Flagstaff seems to see no need to reinforce the outer wall area where the lower pivot ball is mounted to obtain maximum torque with low-force gas springs.
Whatever you come up with please send me your findings and conclusions, especially when road tested. This is still a new concept and the feedback from the factory installations is just coming in. Sounds like using the lowest force gas spring is the key to success. This could mean using longer springs at the maximum distance from the pivot end.
