Thank you for your interest in Water Pumps Direct. Both pumps are of excellent quality and should handle some field abuse. The Subaru model is a bit more protected with the roll cage frame and the Honda does have the installed wheel kit for easier mobility. Obtaining replacement parts for both units should be fairly easy too. If you care to verify that fact, you could call the manufacturer tech support line at the phone numbers listed below.
Honda - 770-497-6400
Subaru - 800-277-6246
