Expert Reply:

All of the replace inner square tube adapters that we carry like # KPG5-Q25-IP are 4 inches square. But there is an option none-the-less. You could replace the entire coupler, inner and outer tube, with something like # BD0289590300. Removal of the old coupler and installation of the new one is going to require a qualified professional with experience in this sort of job.

If this is not an option for you I recommend a different sort of adapter, one that fits in the truck. If your 5th wheel trailer hitch is the type that fits in above the bed rails, you could just get a gooseneck plate like # 16055.

I have included a link to an FAQ article that covers adapters for you.
