I also have an Aluma, but it's only 12' long- I guess the wheelbase of my lakester is less than yours. I bought 6' aluminum ramps with it (which store beside the lakester's front wheels). I mounted a bumper jack to the tongue to allow jacking high enough so the ramps are in line with the trailer floor, to avoid scraping the belly of the race car. Also added "feet" that slide down at each rear corner, so when tilted up the weight is on three stable points, not the tires. I use an electric winch connected to the battery of the break-away brake system- since it's normally plugged into the tow vehicle (to maintain the trailer battery), winch power comes from the tow vehicle's system. Using starter relays, I put together a DPDT switch for the winch, so I can have a light-gauge wire cord with a remote switch- about 25' long to be 'most anywhere while operating the winch.
I like the Aluma trailer. But I realized after first loading the lakester that the trailer (3,000 lb. rated) was not intended for the load (about 2,200 lbs.) to be only at the extreme four corners. I had to make up steel strap trusses (1/4" x 1 1/4" strap?) above each side to keep the trailer from flexing. They are pyramid shaped, about 16" high in the middle, with threaded rod anchoring through 5/8" thick aluminum "plugs" at the ends of the trailer rails. This works well- trailer bed stays flat now. [In the photo, part of the near-side truss is visible (painted black) just behind the stored ramp]
