Did you have the elevator trim set for nose up or nose down? Kidding, glad it all worked out for ya. By chance, did you check the tong weight? we want at least 2/3 or more of the load weight forward of the axle or axles center. or else you get out of control easy like a tail dragger

I have also move other trigear RV's on trailers (many times) with just straps on the tail and had no problems.

I have also seen RV-12's get damaged doing so. It has lighter skins (.020) and a lot less stiffening structure because of the nature of its light empty weight. Another big difference is the rather large (heavy) counterweight used to counter balance the entire stabilator.
There is no way to know ahead of time what the interaction between a particular trailers suspension, and the airplane will be. It is for this reason that I always recommend a tail prop rod.

Nothing wrong with that trailer, other than being a bit too narrow. When you think you have enough straps securing your plane, add a couple more. I always use extra in case one or more should fail.

The RV12 empty weight is ~750 pounds and the trailer is around 250 so total would be just over 1000 pounds.

The new trailer is probably 1800 pounds so probably under 3000 pounds.

One way that I've used to secure an airplane fuselage to a trailer is to partially deflate the tires, wrap rope snugly around the axle and some nearby hard point on the trailer, and then bring the tires back up to pressure. It's definitely secure to the trailer then.

Cool suggestion if you don't use racket straps...

The key in Dons post was the CG. A trailer with aft CG and a high mass center will go into a wag and scare the C R A P out of you. I learned this with a '47 Crosley on a trailer when I was 15. Had to drive 20 mph. Funny, that car was only 3 yrs older than me at the time.

Ha, yeah, probably so. That'd be a very lightweight car hauler, but even so, the tow car probably is not rated for any towing. Good thing there is margin in designs...
