Hy Mr chalmers, welcome, I'm not sure what "help" we can provide, I think I can say with certainty that a person of your size would not be comfortable in that cab for very long, if at all! There have been a few people who have stretched cabs to make them more comfortable, but depending on how that is done it can be a very big and expensive job. I would think that the first cab design that might accommodate someone of your size would be a 55B or 2nd design, but not an LCF, hope that "helps".
