Fitting stabiliser

[crankedup]

Looks like I will have to buy a stabiliser for my vintage outfit. Caravan tends to sway about no matter how its loaded up. Its a vintage outfit dating from the 1920's so stability wasn't top of the agenda back then I guess.
Looking at the Bulldog 100q, any other suggestions / advise.

I use one of the Blade type ones on my outfit. I've tried with and without it, and it definately has an effect, especially at higher speeds with windy conditions. I can't remember the make offhand.

Thanks, my combo has an eye/pin hitch as original, I am advised that the Alko pin and ball hitch is not suitable for use with a blade stabilizer. Problems problems problems.
