Hi Dave,
Our 1969 Bon Voyage was pretty close to the ground, having been designed to be towed, not by modern SUVs and trucks, but by the power cars of the 1960's. Jack stands have always made me a bit wary, especially if you're going to be doing any heavy torqueing, prying or hammering. My solution was to take some scrap 2X6's from an old deck, and construct a simple, but stout, pair of box ramps long enough so both wheels per side would sit on a flat. Then all I had to do was pull or back the trailer up on the ramps and block the wheels. If it was just a quick job, like bleeding the surge brakes, I'd leaved it hitched to rely on the TV brakes. The box ramps gave me about a foot in extra clearance and crawl room.
I know there are molded ramps available for raising a car off the ground for work clearance, but I'm not sure I'd trust them under the weight of a trailer.
Good luck,
Jim
