Loading of a car is different to loading a van. The van has one axle (or at best 2 v close together) which has to contend with the c of g perhaps being elsewhere, the car has two and the c of g falls in between them with the axles designed to hack the load. Isn’t weight over the axle what is always being argued on here? Therefore with its spread axles it is inherently more stable and if one of the two has to bear the load the car is a more suitable candidate and the nose/back end point doesn’t really fit.
Some people mistake a change in handling due to loading (presuming they haven’t overloaded and have prepared the vehicle) as dangerously unsuitable to bear that load and see changing their driving habits as living on the edge. Not really so I wouldn’t have thought.
Then you’ve got the van. Whatever you choose to put in it, there’s no escaping the fact a vast proportion of its forces are acting through the back end of the car. Depending on the weight in the van you'll get different types and levels of forces acting but if you’ve lawfully and safely opened up the margin between the van and car the dog stands more chance of wagging the tail.
I actually worked out all of the weights etc for two of us, 3 dogs , aquaroll , porch awning and other bits stowed in the car and whilst I can see the value of considering them all "in the van" it doesn’t wash because they didn’t even reach Fords max loading for 4 people and luggage!!
The point about soft suspension is spot on. I’ve had tow cars that sagged when you whispered “caravan” and others , including my Mondeo that dropped half an inch then put up with it (until the springs were worn) That’s probably the most relevant part of it overall. Many folk use big older cars for the tow. When were the springs last changed? I can guarantee on the average car after about 5 years / 50 000 miles, especially if you’ve done much towing, swapping the originals will have a positive effect. Been there done that on a “serviceable” Mondeo as a last chance check and the difference was superb.
Bertie, don't you mean ' forward of' the rear axle ? I agree but I did say 'Not as CRITICAL'. as with a soft sprung saloon.
Daved, bearing in mind you already have a considerable downward force exerted on the rear of the car by the caravan, then why add to it by loading heavy kit in the boot. This practice can only reduce adhesion to the road by the front drive/steering. Surely it's far better to load forward of the rear axle thus compensating for some of the loss off traction caused by the presence of the van. As for being within the loading limits of the car, this is not the issue. If you give it some thought you would not load your caravan rear end heavy even if it is well within its weight capability, would you ? My contention is, that by loading forward of the fulcrum point the load is spread between front and rear suspension and not totally imposed upon the rear. Hope I've explained the theory. Am fully aware that this practice wouldn't always work for those with families as the space just wouldn't be available. It always worked for us as just the 2 of us and always made use of the rear foot well. Also carried awning on roof rack mounted as far forward as pos.............Mick
Absolutely on the ball, Mickeyb. I must have been having a bad hair day; I did indeed mean FORWARD of the rear axle.

One other piece of advice - don't travel at speed over 50.
Not a practical suggestion; unless you are advocating that everyone should travel at 50 mph max. If not, then you are going to immediately upset the ones who would complain about "crawling at 50mph" holding up those who want to do 60 mph.
