So I'm getting a 1000w inverter

Make sure to size the DC wiring correctly for the inverter size, and don't skip the fuse. On my last rig I installed a 1750w inverter with short (4') 2/0 wire and I believe a 200 amp fuse. 2/0 cable was overkill in my installation, but longer runs require larger wire. Welding cable seems to be the most flexible and is easy to work with. DIY with crimper, or have the cables custom made (many places do this).

Here's some handy DC Cable Sizing Information provided by Blue Sea Systems I used when selecting 4AWG for my own 1000 watt inverter installation. Since I chose to locate the inverter in the trailer's front pass through storage area the shortest I could make the runs from the inverter to the tongue mounted battery was 6'. That's longer than I would have preferred and although the system works fine next year I think I'll go up a size to 2AWG simply to reduce voltage drop under heavy load but I haven't found any locally in that length already terminated with lug connectors. Welding cable is one idea, perhaps a battery charging cable cut to length may be another.
