Hi John,
Seems like this original post went off in a fun direction but I wanted to throw my two cents in regarding the original question, and I'm looking at it from a different direction. The Oliver LEII is expensive, no question about it. It took me three years of delay before I finally laid down the money. The delay was to get confident that it was worth the money. I told myself that I could very easily get a Jayco for half the cost and be done with the whole matter. But, I was working hard at my job, saving my money, and continuing to look at other companies. When the time came to order, I went with the options I wanted (including the Lithium Pro) and tried to ignore the price. The way I figured it, I'd already decided to get one of the most expensive trailers on the market and didn't want to have any regrets down the road. So, if you want the Lithium Pro, go for it. I love my setup and it's worked very well.
