The wire runs from the front of the truck, to a relay, into the fuse box, then to the battery.

Just run your own 4 or 2AWG wire to the battery separately. Without seeing what this snowplow setup looks like it's hard for me to just recommend using it. You can make your judgement call though.
Are you mounting this inverter somewhere in the cab of your truck or are you just going to wrap up the cable and plug it in whenever you need it, when stopped? If you're going to install it, do it right; but if you really use it very rarely then you can almost get away with taking some 4 or 2 AWG booster cables, chopping the other end off, crimping on some lugs and bolting that to the inverter as a very temporary solution. This would be the workable version of your alligator clip idea.
I used 4AWG thermoset welding cable for my actual run, since most of the current that it will deal with is surge current and not sustained. The welding cable is rated for very high temperatures so they will handle 100+ amps without breaking down the sheathing, and the wire is not run in enclosed conduit which would derate ampacity. If I were to run constant maximum power on the system for 100% duty cycle, I would have definitely sized it with a fair margin. For example when I set up whole-building UPS systems (rectifier > battery string > inverter) which are running 24x7/365 I would do that. (But those run at more than 12V to reduce current)
