Red face Roof box help pls

As part of a masterís in engineering, I am looking into the possible redesign of roof boxes. It would be a real help if you could answer any of these questions for me.

1) Why did you buy a roof-box in the first place?

2) What qualities were important for you in selecting that roof-box?

3) What items did/do you store in the roof-box when in use?

4) How often did/do you use the roof-box?

5) Where did/do you store the roof-box when not in use?

6) Do you interact with the Roof-box (have a use for it) when it is not on the roof of your car?

7) Do you find putting the roof box on the car can be a hassle?

Thanks very much for your help

We had a roof box on the MotorHome when we bought it. We used it for one summer then took it off, it has never been used again and hangs in our garage alongside the one for the car from when we needed it for family holidays.

They are bulky, flimsy and not easy to either use or store. Some open from the back, others from the side but all are a PITA IMO.

They may be OK for bulky items but they increase drag and fuel consumption. In the case of the MH it also took us over 3 m and into a much higher category on French autoroute, and caused problems on ferries.

Putting it on is a major hassle; get the roof bars on, then try to clamp the roof box using awkward U bolts through hard to reach holes, then tighten the nuts with reinforcing plates on the inside where you cannot reach them. Not an easy job or one that I enjoyed.

The waterproof nature was always poor, the overlaps are too small to ensure heavy rain cannot be forced in, so everything needs to be packed in plastic inside - environmentally they are a disaster.

On the MH, using it meant carrying the article up about 3m to the roof, not easy on the narrow, vertical ladder, then carry forward to the box and insert. Repeat that for each article. While parked the box heats up in the sun, potentially damaging contents eg clothes or food.

There may be better versions but once bitten twice shy, I will not use one again. They now both hang in the garage with the headlamps that we exchanged when we came to France. They are good for that, but a plastic box from ALDI would be much cheaper....

Any typo that I make means the errorists win.

Any comments above are only MY OPINION and should be read as that.

Agreed Dave. We borrowed one but soon gave it back. Never again.
We had two massive ones on an RV roof and never used them. The racing team had them full of hospitality awnings.

This one was bought in 2002 for a holiday and is at the moment stored in the workshop, it has been used twice, once for the holiday and once to pack everything we needed for the Navajo when we collected it in 2015, they are a pain in the rear to pack, you either need a step ladder or 2 very strong men.
I shall sell it or give it away when I find someone who wants it.

Some people have a similar thing on the rear rack of a motorhome. You might like to do some research into those if you really are interested in redesigning roof racks for motorhome use. You would need to look into the subject of weight carrying in motorhomes as one has to be careful not to put too much weight on the rear axle. Things like MAM - Maximum Authorised Mass and MTW - Max Train Weight all have to be considered.

I've had two roof boxes (on cars) over the last 20 years so here goes:

1) Why did you buy a roof-box in the first place?

Two adults, four children, au-pair, three cats, numerous hamsters and luggage wouldn't fit into large people carrier (galaxy)

2) What qualities were important for you in selecting that roof-box?

Space followed by ease of access.

3) What items did/do you store in the roof-box when in use?

Anything that I could manage to lift up and fit in.

4) How often did/do you use the roof-box?

Once a month when we went away.

5) Where did/do you store the roof-box when not in use?

In my garage

6) Do you interact with the Roof-box (have a use for it) when it is not on the roof of your car?

No

7) Do you find putting the roof box on the car can be a hassle?

Yes

Here are some general observations:

The first roofbox I had was a relatively cheap medium sized one from Halfords and the second one (5 years or so later) a top of the range, largest box that Thule do.

Undeniably you get what you pay for but the features that I particularly enjoyed from the Thule box were:

1) Ease of attaching to the roof bars. I could do this with the bars in-situ because the Thule box hinged on both sides but with the cheaper box that hinged on one side only I couldn't reach far enough inside it (despite being on a step ladder) to secure it to the bars when on the roof. I therefore used to attach it to the bars first and then, with help, lift the entire assembly in to place on the roof of the car. Vice versa to remove it.

2) Hinging on both sides with the Thule box was also helpful sometimes when parking but not essential.

3) Means of attaching the box to the bars is also relevant. Thule box had simple "claws" that attached whereas cheaper box required bolts and nuts.

4) Capacity is obviously dependent upon needs but without a box we wouldn't have made many of our journeys despite being in a seven seater people carrier.

Happy to answer further questions if you want to pm me.
