We purchased our Jayco Bungalow back in May and put it on a seasonal site. It is also considered a Destination Trailer. It is 40' 2" long. After getting ours on site and all situated, I used a bottle jack between the axles to lift one side. I used 5 cinder blocks and made a "tower", one in front of the front axle and one behind the rear axle. I also placed a piece of 2x6 pressure treated on top of the top cinder block. Then on the other side I did the same thing. However, I used gradually thinner pieces of 6" pressure treated until the camper was level.
After letting things settle for a month, I went back and re-leveled with different thickness 6" lumber. We have stabilizer jacks at each corner. I used 2 cinder blocks under each so I only had to extend the stabilizers about 6 inches.
I know you mentioned in a previous post that you already have a deck on site. You can use the same technique to raise the camper to the level of the deck if that is desired. Just lift one side at a time.
When we get back to our seasonal camper, I will re-level. Hopefully it is done settling after 4 months living in it.
