Thanks Michael. The pictures are worth 2000 words.
That is the same way I jacked up my previous trailer, but I wanted to make sure. The first time I jacked up my previous trailer, I put the jack under the axle where it connects to the frame. I lucked out and nothing happened to the axle.
I bought the Flagstaff at Berryland Campers in Ponchatoula, Louisiana.
I really like the Trailer-Aid. I may look into that.
After having to jack the trailer up in a parking lot in Bennettsville SC in 90 degree weather to change one of my wonderful Carlisle tires, I ordered the trailer aid. I hope I never have to use it, but I have it. I'll have brand new tires on it soon. They won't be Carlisles.
