Daf T244 Build Planning

Postby steverjuk » Thu Aug 16, 2018 5:20 pm

Hi
I'm currently planning out a build on the back of a Daf T244 and just wanting some input. I've designed this box structure to fit perfectly the back of a Daf T244 with no overhang 4190mmx2340mm.
I'm planning to use 50mmx50mmx3mm box section for all the structural work and then clad it with 3mm Aluminium. I've currently gone for the design below and just wondering if you would suggest more cross braking? I've tried to have as little cross braking as that way it give me more option to put windows in and also add access panels into the box etc. The

Hi and welcome to this little group,

I would have thought with all that steel work it would be overweight before you even start. How much will that lot weigh? May I ask why you wish to use a steel frame? Some of course do use steel, some ali and some, like me, use composite material.

How were you planning on installing the "box" onto the vehicle?

Are you aware of the Adventure Overland show coming up in September? A great mass of very clever people will be there if that helps with your thoughts? Well worth a visit.

Hi Brain
I've run the numbers and with steel its going to be around 450kg, as the truck can carry 4000kg I'm going to be fine, i would have thought.
I'm using steel as I can get it super cheap (based in Sheffield), I know how to weld and am used to the material in the past so I know it. I thought about going for composite but cos t / not knowing it kind of put me off.
I was planning to build the box on the back of the vehicle, but mount it in such as way that if I ever need to remove it I could using a fork lift. I'm off to the overland show with my Land Rover group, so planning to pick people brains.
Just applied for my C provisional license, so hoping to start the build end of November.

Look forward to seeing you at the show then! Excellent.

One thing I should have mentioned is, register the truck before you convert it! You will very much regret it if you do not, believe me!

You say in Sheffield, I am to the East of Beighton, Wales Bar, if you want to pop over for a chat? S20 area.

Have fun,

B.

So you suggest registering it as a private HGV, then doing the switch to a motorhome?
Sure I'd love to pop over and pick your brain, so many questions about the DVLA, licensing, servicing etc.
Have a few questions regarding insulation and venting. Thinking of going down the 50mm celotex route with then a few mm of closed cell foam over that before the marine ply. Just wondering if that's going to be enough when we take the vehicle to Finland etc. Also I've seen talk about correcting venting the cabin, to stop condensation etc. Am I correct in just having a few floor vents in the cabin should be enough?

Hi.

Looks like a great project.

I would definately go and see Brian about registering it. Going staight to motorhome is not the right route. He is our expert.

Brian makes the bold statement that his kettle is always on but I didnt get a cuppa so you need to push him on that.

Good luck and keep the updates coming.

Neil

You little liar Neil, my kettle IS always on but only my friends! So that is you and Phil out straight away!!!! Luv ya really!

As for being an expert ant anything.... that will be the day!

Definitely private HGV first, you may like to read my "report" here http://home2roam.uk/wp/registering/ one of the few blog's that did not get hacked that I lost.....

I think the vents in the floor you mention may be for gas "drop out", these are vital and probably a legal requirement, but as you say, ventilation is vital and I find I have my windows open quite a lot which works, and as I have covers over my windows for off road protection, I find I can close said shutters and leave the windows open inside... that works.... the shutters do get condensation on them but it matters not a single bit as they are outside.

You can come over and have a chat at most any time, just give me a call and we can get it sorted, there is loads to discuss when starting and during and after! Never ending!

Have you got a copy of Steve's book? Worth every penny!

Hello and welcome.
I'd re-check your weight figures, 3mm aluminium is about 8kg/m2 and 50mm RHS is about 3.5 kg/m.
Building like that I'd expect at least 750kg for a box ready to furnish, and about 1 Tonne + ready to use.
Are you planning to put the box on the existing bed?
If so I'd consider ditching it, with a couple of 100 x 50 longitudinal members you could go with a rail on rail set-up.
While the truck may be able to carry 4 Tonne, I'd load it with 4T and see how it drives and handles off-road, I suspect you would pay close attention to weight afterwards.
Sorry to sound negative, but weight is important, even with a truck.
I agree with Brian, if you haven't got Steve's book then get one, it will be the best £20 you'll spend on the build

Brain,
That's my plan get it on the road as a private HGV asap, I know I'll have to add the side under run protection and maybe the rear depending if the inspectors know about the 4x4 dispensation.

Reading Steve's book on it he suggest putting floor vents into the box to allow for fresh air to circulate, I'm going to go with a underslung lpg tank to get around the need for a vent for that.

Love to pop over when you have time, it's always good to have someone with experience, as they have already made the mistakes.

I've already got Steve's book and must admit it does answer some questions but I'm annoying and have even more.

Hi Ivan

Per the info I've got from my modelling software

2430mmx1060mmx3mm Alu Cladding 4
2430mmx1085mmx3mm Alu Cladding 4
2436mmx1060mmx3mm Alu Cladding 2
2436mmx1085mmx3mm Alu Cladding 2
50mmx50mmx3m 2340 45s 4 (9360)
50mmx50mmx3mm 1010mm 16 (16160)
50mmx50mmx3mm 1490mm Crossbrake 4 (5960)
50mmx50mmx3mm 713mm 5 (3565)
50mmx50mmx3mm2.2m 20 (44000)
50mmx50mmx3mmx4290mm 45s 4 (17160)
50mmx50mmx3mm 1307mm Crossbrace 3 (3921)

Total 100126mm

Steel 101 m of 50x50x3, so about 430kg in steel.
Alu 14 panel at 23kg 322kg

So 752kg total, so yea I was a little out, as I thought it was going to be 400kg without the aluminium but if I drop to 2mm panels it drops total to 591kg and if i drop to 1.5mm panels it drop the weight to 537Kg.

I've edited the post above as I didn't make it clear what I was stating the weight of, it sounded like both skin and frame, rather than just frame.

Also I'm planning to use the existing bed but remove all the wood off the bed that should remove a few kgs of weight as well.


Do you suggest I leave the Aluminium at 3mm or drop it to 2mm or even 1.5mm? Will it make that much difference, seen as if I full up with 400 litres of water then I've already destroyed all those weight savings.

For me, I'd save weight where possible.
3mm does seem a bit on the thick side for cladding, though I suppose it depends on your intended usage.
Maybe find out what thickness a Zepplin shelter uses as an an outside skin and use that as a guide?
I'd still give consideration to ditching the load bed and putting a couple of rails on the bottom of the box.
Brian will be able to give you an idea of the weight involved in the bed.
Best to ask all these questions before committing to anything, rather than half way through :D
