A few minutes ago, I PM'd centerpunch the following but I thought it may be best to share with all. The net is that I now have a LOT of trailering experience - especially wuith the GT's and I am very biased on a set-up that works extremely well, is very safe, and is very efficient time-wise. I think NOTHING of loading up a client's GT in the trailer for even a short 12 mile jaunt over to the dyno. Loading, transporting, and un-loading is just so darn easy that it is no bother. Here's my thoughts....
The best trailer, IMHO is a Featherlite v-nose aluminum trailer - with NO DOOR. If your Featherlite does not come with it, add e-track to the floor. E-track kits can be purchased from E-bay inexpensively. The e-track to be spaced such that the tires of the vehicle you will most frequently transport will be in the miiddle of the e-track. Purchase a battery, battery hold down, winch, and winch remote (recommended) and install in the front of the trailer. Since we haul primarily GT's, I off-centered my winch to align with the tow hook position of the GT. Wire the battery such that the tow vehicle will charge it while towing. In 2 years, I have never charged the trailer's battery and the trailer spends most of its time parked in storage. Put a battery disconnect switch for safety between the winch and battery. Buy the e-track, over-the-tire tie-downs from Summit. Get 4 of them. Finally, if not equipped on your Featherlite, add a 12" aluminum flap extension at the end of the ramp with a piano hinge.
This is the "tits" set-up. Loading and un-loading is an absolute breeze. You will be the envy of anybody loading/un-loading and I guarantee you will will do it faster and safer than any other configuration. Here's the procedure:
1. Park the truck/trailer on level ground or in a slightly up-hill orientation. If only level, induce an uphill orientation on the trailer by winding down the trailer's jack - while letting it remain hitched.
2. Drive the car partially onto the ramp, centered as best as possible and set the parking brake.
3. Connect the on-board winch to the car and take out the slack.
4. Release the parking brake and turn the key on so you can steer the car through the open driver's window.
5. Winch the car making small steering adjustments if needed. The e-track will help you to align the car side to side.
6. I leave the front-side of the front right strap attached to the e-track as a guide for how far to pull the car in, stopping 1" from this cleat.
7. IMPORTANT: Temporarily disconnect the battery from the winch with the battery disconnect so no accidental winching with car strapped.
8. Place and cinch down all 4 over-the tire straps.
9. Reconnect the winch to battery and give it a tad of slack. Diconnect winch from battery for transporting.
10. Remove key from car (set parking brake if desired).
Unloading is even easier.
1. Again, orient trailer in slight up-hill orientation.
2. Remove 3 over the tire straps leaving front-right for last.
3. Connect battery to winch and then remove last strap.
4. Release car parking brake if set.
5. Use remote to let winch out and car will back out of trailer - typically NO steering adjustment is needed.
Why I like the Featherlite over other trailers and set-ups:
1. Beavertail in floor makes for very low-angle ramp. I routinely load lowered GT's with NO boards or ANYTHING else. Just my 12" flap extension.
2. Winch eliminates need to crawl in and out of car through the door.
3. No trailer side door means lower deck height and lower (safer) cg while towing.
4. Aluminum construction means the trailer is light for towing.
Anyway, I hope this helps. Why don't I like the side-door trailers?
1. Deck height is very high to clear wheel wells to allow the car's door to open.
2. High deck heght requires long ramps and storage/deployment time/energy.
3. Low ceiling height (sometimes)
I can load or unload a GT I would say in roughly half the time with half the energy.
Now you have my biased $.02.
