Hello Guys and Galls,
I am picking up a new to me caravan on Saturday and I have a simple ish question for you, I have a Ronbox Synergy 2a fitted and I am currently running it on setting number 2,
I had it 5 for the fun factor when I first had it fitted but 2 is the best all round for my everyday driving, but with a caravan on the back would I be better running it on;

Torque/Performance

2. Medium/Medium
3. High/Medium
4. Medium/High
5. High/High

My guess would be either 3 or 5,
but if any of you guys have experience on what works best I would love to hear from you..

PS Car to Van ratio is about 55-65% so not a big weight to pull
Mass in Running Order (Kg) - 711
Maximum Allowable/Authorised Weight (Kg) - 900
Shipping Length (metres) - 5.35
Width (metres) - 2.19

That's a tiny light weight van.

If if doesn't smoke, try it on 5. I never towed with the Ronbox when I had it, as I remapped the car while back. My remap was fine. It coped with the 10% hill I threw at it with no problem in 3rd at about 35-40. The road was too bumpy and wet to go any faster. The van I used was 960kg unlaiden and 1200 approx max.

You shouldn't have any problems with that light weight. Even on 2.

I tow a swift weighing 1450 kgs . I have a td4 standard apart from silicone hoses and egr blank and it pulls like a train with caravan on the back

Its A Bailey SE Maru 1993, not sure the weights are correct but I used this to do the calculations for me..
