Tributary 14hd- Frame setup options?

Hi everyone! I'm new to the forum. Long time boater here, most experience is with C-boating and kayaking, although I did guide rafts for a season and have rowed the GC in a rented boat. I'm working on building a raft rig to get into multi-days with my small family.

I'm looking for frame recommendations for a Tributary 14HD. It only has a 68" flat surface area. So far, I am considering the NRS Bighorn I. Anyone running this setup and care to share pics/advice or rig details? Any other...
