So I have been debating for months on what I want and what I can afford and such. Last weekend I bought a northstar 13000 ppg off of Craigslist. It is older than I thought, I thought it was 10 years old and it turned out to be 15 years old. But it is a commercial unit so that doesn't bother me. It runs good, I have a new set of plugs, new fuel filter, and oil change to do today, along with filling it full of new fuel. The problem I have with it is weight. I keep it in my spare garage and it has to be plugged in at the other side of my house, about 50 yards and you have to go up a hill to get there. The generator empty is about 400 pounds. Throw oil, 10 gallons of gas and such and you are around 475 pounds. On concrete it doesn't move too bad, but on any other surface it sucks. So I am thinking of buying a cheap trailer from harbor freight and permanently mounting the generator to it. That itself wouldn't be hard. However I would like to make it weatherproof as well so I can run it in the rain or snow and not have to worry about it. The other reason I would like to do it is to make it a little quieter to lessen the chance of people stealing it and keep it a little quieter in the house. I have watched video after video on YouTube and read different forums on the subject, all of them build enclosures for the generator, but they are all stationary, none on a trailer. If I wanted to never take it on the road that would be fine. But if someone needs to borrow it I want to be able to take it somewhere, so the enclosure would need to be road worthy as well. I know that I will need to figure out someway to vent heat, a way to change the oil, and a way to add gas to it. I'm mainly looking for anybody who has any ideas on how to accomplish this. I have a few ideas but that is about it, I don't know what materials to use for the enclosure but I'm leaning towards thin plate steel. Here is the generator and trailer I'm leaning towards.
