Unfortunately, your best bet is to replace the entire floor with one solid piece. We did that last year in our
Sovereign. It was no piece of cake, but we are so glad that we did. The previous had tried to piece together a new floor by cutting different sections and fitting them in. The gaps were filled with caulk. It was a real mess.
We have pictures buried in our digitial "vault". I will try to get hubby to email you if you are interested.
