If you need a leveler there is a neat product made by BAL called the single axel leveler, and it's a little chock that you slide under the tire on teh low side and crank it up, and it lifts the tire until you're as level as you want it. We have one for our Caravel
and we LOVE it!
As for the jack stand, do you mean the foot for the jack on the tounge? I like the looks of the one on vintage trailer's site. I was thinking of picking one up myself. It looks nice and tall. It would save you some cranking!
