(Sorry for the late update guys. Just not long had my tea as a really busy day - shattered)
Well I took the car trailer out loaded with the car, 8 wheels and toolbox - ( 2 tonnes). Was on the duel carriageway with the D5 and all seemed fine at 50 mph and 60 mph. However took it up too 70mph and it did not seem as steady or surefooted as the D4 did. A bit of sway from the trailer rear, but nothing overly alarming.
(I took the D4 too Germany last year with the car and my Yamaha R1 as well, both on the trailer, heading too the Nurburgring. Sat at 100mph plus on the Autobahn all the way and the car never flinched - steady as a rock)
My brother took over and also found the same happening. Nose weight was fine all 4 tyre pressures fine on the trailer and checked car tyre pressures which were also fine.
Decided too take his D4 out as a comparison and it was steady as a rock at 70 mph. I then drove it on the D4 and it felt alot more surefooted at 70mph. Never missed a beat.
Really puzzled as last weekend pulled 2 tonnes in home made trailer single axle, no problem whatsoever in the D5.
Only conclusion is that the car transporter is quite a bit longer than home made trailer, hence understandable the swaying issue. I also took out the small trailer for the kids quad bikes and it towed no problem.
Well maybe it's possible that the softer wallowy suspension on the D5 is causing a conflict, as the D4 rides alot less boat like. Hence the issues with the majority of the Caravanners on here. I also noted that with the smaller trailer it was not an issue at all. Seems the only issues as far as I can see is that it's the longer vehicles that are causing the issues not the smaller ones which are being towed.
Would have been good if LR had reintroduced the ACE system too reduce roll as I think this would have helped stabilise any swinging. Or if the car,
when put into sports mode automatically stiffens the suspension too eliminate body roll.
Possibility the 480 kg loss and monocoque chassis may also contribute too the issues.
Again the deployable tow bar may be an issue. I dont know what it is but am not overly confident with it compared too a fixed one. Again I had issues with the damn thing not deploying and part deploying and trying too disemploy with the trailer still attached
Anyway that's it in a nutshell am afraid. Too summarise it could be any of these issues I think may be a problem or a combination of all of them.
Towbar type
Soft suspension
Longer vehicles being towed ( longer than the D5)
Chassis type
Weight loss of 480 kg
Stay at 60mph or 70 mph max if overtaking is my advice
Mind you this does not mean my test run is 100 percent accurate, as it may vary depending on the drivers driving style or on the individual car, the way it's been set up etc.
Also my sons go pro somehow dislodged itself and its wrecked, so can't upload any videos. Someone must have ran over it on the road and its been pancaked. Well gutted
Take note LR, am doing towing test runs on your behalf, and ruining my equipment in the process
