    50 Amp Service Question

    In this case, the 180 degree shift is nothing magical. It is simply polarity. It means that the ends of the coil are equal and opposite at any instant of time. In this exact same sense, the poles of a battery are "180 degrees" opposite. North and south are "180 degrees" opposite. In other words, somebody used the term 180, and it happens to have the same phrasing as the 120 degree shift used in 3-phase terminology, except it really doesn't mean a phase difference any more than north or south are out of phase.The device that creates it is the transformer. At any instant of time, current is flowing in one direction, and therefore the magnetic lines of flux have a specific polarity, driving a current in the secondary a certain direction, creating a positive potential on one side and negative on the other. In the next part of the cycle, the polarity changes, so negative becomes positive and positive becomes negative.In other words, at any instant, one wire is positive and one wire is negative, thus the idea that they are "180 degrees out of phase". Found this explanation. Hope it helps with your question.

    2018 National HDT Rally, who is going to be there?

    I dont teach high school kids but rather train them in my business after high school. And, yes they are needy, and SHORT ATTENTION SPAN. Want a paycheck but work on their phones more than at the job. This is construction, dont get paid by social media. Have to get the job DONE to get paid. In between LA and SD, Riverside County. Likely take the 15 to the 40.

    Multi tasking may work for some things but certainly not all things. Good thing I havent left yet and decided to follow your directions from earlier

    2018 National HDT Rally, who is going to be there?

    We are changing our plans from rental car(due to selling the DRV) to working on packing the Teton(once we get it home) then towing to Hutch. It will need tires, which is why I am asking about recommendations. Hopefully it all goes well and we will be staying at the Fairgrounds, but backup plan is rental car.

    New RV tire changeover ?

    Thats the direction I am looking at Glenn. Your math is about the same as mine. Purchasing from private party. I will put the tires on it that I want.

    Thanks. Seems like you would know that route. Bought a Teton yesterday in Tarzana. Near you So Cal place.

    New RV tire changeover ?

    I just bought a 33' Teton that has 7YO G614. I had these on another 5er and had blow out problems. Given the fact of their age, will be changing them over to something else. Seems that Sailun are proven by some here, but we arent opting to step up to 17.5" mostly due to the size and weight of this coach. I think I still have some capacity left in the 16" G rated tires. Heading to Hutch for the National Rally next month. ~3000+ miles What have some of you found that worked for you and where did you find the best deal? I have local tire shop to do the exchange.
  10. I have seen products that can be sprayed on DG or other small gravel to tighten it up and can make it like a compacted gravel. Appearance is more like exposed aggregate concrete without the cost. I might also suggest getting a plate compactor at a rental yard to tighten the gravel up a bit, then spray the product. As for chocking the tires, the X chocks might do the trick but I prefer rubber chocks like what is sold at Harbor Freight(I have some) and I use Rotochocks too. The rubber chocks are good for the coach movement forward and back, the Rotochocks are good for reducing the shaking in the coach.

    rv trailer values.

    Kirk is right on. There is a show on cable that shows people going through the RV buying process. I have yet to hear ANY of them comment on chassis, drive train, structure, roof, solar, etc. Instead its all about the decor, the appliances, the colors, the mattress, things like that. I would prefer to buy used with good BONES and then remodel. That way we get the colors we prefer, the flooring we want, the appliances that work for us, things like that. Yep, keep it till the wheels fall off, but hopefully that doesnt happen due to lack of maintenance.

    Considering that reports usually show that new units depreciate when driven off the lot, 20-30%, sounds like it might be a wash, value wise. BUT, then considering the quality of newly made units, both from the assembly/workmanship standpoint and from the components (stove, AC, cabinets, etc) standpoint, might be better to buy used and then remodel to your own taste, but that assumes you get a quality used unit.

    Let’s Discuss Harbor Freight

    I have been buying tools from HF since when they started. I buy their hand tools, wrenches, sockets, etc. I NEVER buy their electric tools. I am a contractor and find they dont last in professional service. That being said I also NEVER buy electric tools from Home Depot & Lowes. Many companies make some models for them specifically and they are lower quality although still say the name brand, esp DeWalt. I have found they dont hold up either. Grinders I use Metabo, recip saws- PC or Milwaukee. Cordless has always been Makita and it has served me well for over 30 years- I still have my first 9V set. Cant seem to part with it, even though I dont use it. I have done some testing with impact sockets, HF compared to the name brands and HF has outlasted them all. I used to install pallet racking and running electric impact guns for days, many guys at a time, and HF held up the best. I wore out some Matco sockets, took them back and showed the dealer how it compared to a HF put into service the same day. He was surprised, so was I esp when I remembered what I paid for each. Havent tested HF gensets or welders yet, but am curious about their new BRAND.
