Hey Grigg!
I've read a lot on the forums about wheels, as it seems to always be a hot topic. Properly identifying the RH-5 wheels seems tricky for a guy non-acquainted though; maybe it's best to 'rule out' which wheels they are 'not' as suggested in the Tip. My front wheels are NOT RH-5 due to the outer ring being present?
I'll try and get some pictures of the new 2ton truck (also faded red :)).
