Yesterday I bought the Harbor Freight kit.
# 90599
Sale price of $179.00 USD, with 15% off coupon

Total after states sales tax added
$161.28
This kit has the newer control box, it looks pretty nice to me but I'll just use it as a power panel and use a different charge controller.
Now I'll have to get back to my pipe over pipe, powered with automotive window motor, RedRok tracking system.
But I might just wait for my new to me camp trailer to see about setting that system up with it.
I got offered a 1969 Ideal travel trailer a few months back by a very fine older fellow.
When he heard what I was willing to pay for a little 10' trailer I wanted to buy,($300. new tires).
All I wanted is a mobile shop/shed office, after the last two moves I've thought very hard about everything needing to be on wheels from now on!
He asked if I wanted one that small and told me he would sell me his 18' dual axle for $200., SOLD I said!
He redid the inside two years back putting in a new toilet and every thing else is in working order.
This comes with two propane tanks and a three old battery.
I really should go back and look at this again, I have only seen it from a couple hundred yards away not wanting to walk out to it in 4' of snow !!!
Now that the snow might be about gone and knowing how to get inside, a closer look is in order.
