When I installed the Magnum 2012 in the coach I rewired the entire high current system: Batteries, shunt, central buss posts, solar, etc.
Everything was rewired with Royal Excellene 4/0, and 4ga for the solar. I bought a 12ton Mic-120 off of eBay and it's done an excellent job. Once done, all the crimps are covered with adhesive lined(weatherproof) heat shrink from Harbor Freight. It's a 100% solid seal, and its cheap.
As for the hammer vise, if someone wants to come by and take it, it's free. The two cables I did NOT change were the jumpers between the batteries, and I found one changing by 3/100v on a hard charge simply by wiggling the crimp that otherwise looks fine.
Just be careful that the crimper you choose has the die that can properly collapse a 4/0 lug. You will likely need to do a 2 stage crimp to get where you want to be.


Jeff:
That is a nice crimp, what brand is the crimper and how much did you pay for it?
I came to the conclusion that I would need to buy a bench top unit to do the job properly but that would have been around $400 to take that route and that was more than I was willing to spend.
