We too have the dreaded bubble in the floor near the fridge . Our dealer offered the injection method but doubtful if it would work, 2nd option was to put a small metal strip down on the floor - that wasn't going to happen and the 3rd option is to send it to jayco who wouldn't be available for another 3 months and when they do get it, it would take them another 3 months to do the job. Needless to say i wasn't thrilled with any option, especially since we plan on travelling next year. They have said that when are finished travelling we could get it done then, but i'm yet to get that in writing.
