No, I haven't done it yet. I've been on the east coast again, away from home and all things trailer. I'm heading back home to the west coast next week, and then I'll get back to my trailer projects.
I've got a fairly easy and inexpensive plan cooked up for the inverter. I got all kinds of advice about this project, everything from really expensive to really cheap, and I've decided to go the not-too-expensive route. I couldn't justify spending a ton of dough just to run a blender.
Here's what I'm going to do. I'll use a cheapy 750 watt inverter from Harbor Freight:
12V Power Inverter - 1500 Watts Max
I'm going to create a new 12 volt
outlet inside the trailer using this:
Trolling Motor Connector Kit - 8-Gauge | Bass Pro Shops
I'll replace the alligator clips on the inverter with one set of the quick-connects in this trolling motor kit, and then I'll create a new outlet with that nice and clean, 1 1/2 inch diameter round hole plug and the other set of quick-connects. Is that making sense? The wires will connect to the batteries on the tongue and come up through the bottom of the trailer into the compartment under the street-side dinette seat. That's where other wiring comes into the trailer, specifically the umbilical, which I recently replaced and found that it wasn't hard to do at all. These new 8-gauge wires will follow that same route. I should also mention that I'm planning to install an in-line fuse holder near the batteries, which will hold a 40 amp fuse. Then I'll cut a very small, clean hole in the base of the street side dinette seat and install that round hole adapter. Nice and clean. Then whenever I want to use the inverter, I'll just plug it into the new outlet and away we go. I've already tested this inverter with our blender and it works just fine. The blender is maybe an Osterizer I think, 600 watts as I recall.
I had originally thought I'd permanently install an inverter, but it was getting to be too expensive and too complicated for me to do myself, so I've come up with this as a simple and affordable compromise.
