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.
