New Elddis Sunseeker

If lightly loaded and running with full 70psi?tyre pressures then could be a very hard ride and feel like "vibration" 

Don’t forget you are now driving what is essentially a commercial vehicle rather than the family saloon car. It is bound to be noisier and less smooth than a car. How does it compare with others you drove on  test?

MHs always suffer from rattles emanating from the habitation unit and we all spend time tracing and silencing them. Once they're fixed, the whole driving experience becomes more pleasant. Tyre pressures, too, can be crucial to getting a good ride.

I Drive trucks for a living, unfortunately did not test drive before purchase as was brand new, really is uncomfortable and noisy

So you are very familiar with commercial vehicles. Did you not test drive something on the Boxer, which I assume yours is, before buying your MH?

As JVB said, load it up, if it isn’t already. Get your tyre pressures sorted and if you’re still not happy get it back to the dealer pronto and insist it's checked by a Peugeot dealer but it's my guess tyre pressures are the cause.

The only suggestion I can make is to set the van up into travelling trim. Load all the equipment and personal items you would normally carry, plus 90% fuel and whatever fresh water, add passengers and get the van weighed; total and each axle.  Contact the tyre manufacturer and ask them to recommend the best running pressures.  Normally these will be lower than the book says and will provide a better ride. Good luck.

PS.  Just an after thought.  Has the van been sitting around for a long time unused.  If so the tyres may have taken a set which in my experience will disappear in time, normally after a longish run.  

I must admit that when I first drove a motorhome I was surprised about how noisy it was. But as others have said driving what is an empty box van with a few fittings is is bound to have more noise than driving a car. Once you have got "your stuff" in the van it will be better and you will discover gradually what is causing the noise. A few things to be going on with which will start to make a difference. The glass hob cover usually makes a lot of noise which can be dampened by having a cloth under it whilst travelling. If you have a folding shower door this can rattle in transit and a towel folded over the top can help there. Another thing to look at is the table storage. You will find that poor road surfaces mainly contribute to the noise, drive on a newly resurfaced road and you will notice a big difference. Stick with it you will get used to it and also find ways of eliminating a lot of the noise.

We took ours out for a run round from storage a couple of weeks ago on a very cold day, so totally empty. It was very noisy compared to when loaded and all the fittings have warmed up. We  pulled over a couple of times to try and silence things, particularly the oven. However, by the time we returned and things had warmed somewhat it was a lot better. As others have suggested try it loaded and if possible get the inside warmed.

Driving a truck which these days it seems are mostly fitted very comfortable driving seats sprung or air suspended, is is very different to driving a white van man base vehicle

Our Boxer base was not a good drive when serviced by a PUG dealership as they always (although advised to the contrary in my owners  conversion hand book)put the tyre pressures to what was on the base vehicle door piller

Ps i fitted a sound proofing kit ,and it really made for a much quieter drive (after all the rattles were mostly found) 

We had a real shock when we picked up our new Sunseeker 155 nearly 3 years ago now. Everything rattled from the oven shelves to anything in the cupboards, anything which rattles use tea towels to separate the two surfaces, stuff cushions into the cupboards if the content rattles

We get very little rattling and noise now, loud it is, it’s a van certainly not like a car or a hgv.

if your on fb there is a group called Elddis motorhome owners group which is great and friendly, loads of tips and answers to queries.

I have a two year old 175.

I reckon the drive is OK, actually.  But it is not my first MH!

As mentioned above, it is not quite, as most of the fittings make some kind of noise, until you develop a packing routine that quenches them.

I wouldn't say there is any vibration, though.  Without comparing it is hard to say whether it is normal or not.  In motor home terms, I would say this is a middle of the road noise level unit.
