You got photos of the side protectors installed? I'm curious if they're really needed or not in addition to the floor mat and seat backs.
$1500 is standard for hitch, wiring harness, atf cooler and rear kick opener adaptor. You could order yourself from discounted Honda online dealers and pay trailer shop to install. Just depends how much of a project you want to make it vs having dealer do it and roll into loan.My local dealer (not the one I bought from) wants nearly $1500 to install hitch and cooler on my EX-L AWD. Outrageous.
