Tom,
We had the Pull Out Sofa With Air Mattress. On our first trip out, DW kept having to add air to it the first night she slept on it because of my snoring (telling on myself) She ended up on the floor. The technician I talked to said it was common for them to get caught between metal parts when folding the sofa up. He also stated that the majority of the time it is a seam that leaks. They replaced my mattress and from that point on WE were very careful when folding up the sofa to ensure it was clear of all folding metal parts. Others on here will come along and tell you that they actually remove the deflated mattress before storing the sofa. It is only held on by some Velcro tabs. I believe your sofa is made by
Flexsteel, and they have some finer products. We now have the "Motor Home Sofa Sleeper Model 4452-FB60" by Flexsteel and it would be a fine replacement for the pull out sofa. It serves as a recliner, or full size bed.
Our 2008 (Mfg'd in 2007) 3400RL had the 7000 Lb axles. It should state in your documentation what capacity they are.
