I did the Airlift 1000 Bags. Once I got the old ones out, (the hardest part), putting in the new ones was easy once I discovered you heat the bags in warm water, roll them up tight. and just push them up through the hole in the bottom of the A frame. If I lived closer to Camping World I would have had them done. I understand they're very reasonable. They come with remote fill tubes. Had them about two years and am very satisfied. I run about 85lbs in them and they really stabilize the front end.
