The only thing you gain with the D710 is the TNC in the head to do APRS really easily.
You are correct, that is my mistake. The TM-V71A is a dual band, dual VFO like the FT-8800.
What I don't see is how there is a market for the RC-D710.
TM-D710A is $550
TM-V71A is $375
RC-D710 is $350
So it costs $175 more to adapt a TM-V71A using the RC-D710 than to just buy a TM-D710. If you did already have a TM-V71, it would be much cheaper to just TinyTrak which gets you the TNC as well as the GPS for $130.
