Has anybody fixed a bike rack on the back of a challenger 480 and towed with a Vauxhall Zafira 1.9 cdti 150? Just wondered how you found it.We have always carried our two bikes in the van but we have just changed to this 480 and they don't go through the door and turn the corner as easy.Before we invest in a rack to fix at the back of the caravan we just wanted to make sure it wouldn't affect the stability of the outfit.OH has always wanted one but I am a bit apprehensive.
Don't think it will affect the stability significantly but it might affect the resaleability. I have met people who have unused bike racks but cannot take them off cos they leave unsightly holes in the van.
I would try a towbar or A frame mounting

I was always told this was a no-no on GB vans as they are not strong enough to the rear, unlike camper vans where it is okay. Also there is the issue of having that much weight at the rear of the van from a stable towing point of view, finally it would take signicantly form the weight allowed in your van too.
After checking this out we ended up with a roof mounted rack, we use a towball rack when not towing, but when towing there appears little alternative once stability, nose weight and van loading are taken into account.
My understanding is that Swift vans already have the reinforcement in place to attach a bike rack to the rear of the van. Currently I have a towcar that has the allowance to take a towbar mounted rack but the way things are going with lower and lower nose weight allowance (the new Sorento being an example) a rear mounted rack might need to be considered. It should not lead to instability provided loading of the caravan is done correctly. As regards selling the van on then you could always leave the rack on the van but I am sure there must be blanking plates to cover the fixing points.
tail shake would be my worry with two bikes and a rack on the rear of the van.if not designed for it there could be some instability for sure.ask swift customer service.the weight of our bikes is at least 16 kgs each,plus rack????
------------- the only silly question is the one you do not ask.
It's not something I would ever do. Weight at either end of a caravan is a bad thing. As much weight as possible should be concentrated near the axle, otherwise you get pendulum effect.
The Challenger 480 has a long rear overhang on a single axle, if I am looking at the right one.
I know I would not place 35 to 40 kg set off the rear and tow it with a 1450ish kg kerb weight vehicle.
I am sure you will find those that do, probably including some Dutch, but in my book that weight distribution is fundamentally wrong.
Too much, too far aft, too high up, too light a tow vehicle, and single axle; it goes against all stability criteria.
Ask your van insurers as it is a modification to the van that they might have good cause to consider alters their risk.
Agree absolutely with this. I'm not sure what the overhang limits are on caravans. I know it used to be 60% of the wheelbase on cars and commercial vehicles, but not sure how it applies to caravans.
There's already enough length behind the axle, without adding more.

Surely the pendulum effect can only occur if the caravan is in balance - that is 0kg nose weight?
Surely the pendulum effect can only occur if the caravan is in balance - that is 0kg nose weight? not really a passing transit van can upset any well balanced caravan and once it starts swinging it will want to keep going if the rear end is heavy.car transporters are the worst for this,why? do not know.this is also the reason i will not carry any water on board in the heater or toilet.

No pendulum effect is simply placing weight at a distance from the point it articulates about; in this case the axle.
Balance plays no part, a pendulum can be totally balanced like a dumbbell or totally unbalanced like a clock weight.
Unfortunately those bikes and rack on the back will have to be balanced by forward weight, thus greatly increasing the overall pendulum effect of the van about the axle. As I said earlier its fundamentally the wrong thing to be doing.
So when everyone says pendulum effect they are referring to movement in the horizontal plane around what is the (in aeronautical terms) yaw axis and not to the up and down movement (which should be)controlled by the nose weight?
