I consider myself a factory tour geek and have been to almost all the manufacturers-..(SEVERAL TIMES).( haul trailers to dealers). and I will say pretty much without a doubt (except for spacecraft )..no trailer manufacturer will warrant you towing 6000 lb behind their fifth wheel !!!!!!
(Not even sure SPACECRAFT will).
you will be on your own I can almost guarantee that......You are free to disagree.....but GET IT IN WRITING.
About two weeks ago I did a tour at--Augusta RV and they don't even put a hitch on their fifth wheel (mind you it is a triple Axel very custom-built 5th wheel....$150,000.):E
