Start at the beginning first....VAN WEIGHT.
3.0 TONNE MAX means the vehicle is at its limit and already stressed. Look for a van that weighs 2 tonne and by the time all the sleeping gear, food, fluids, tarps, chairs, tables, leads, water and extra fuel is loaded you will be around 2.5 tonne. A figure that will see an easier tow, less stressed vehicle (and driver), less fuel usage and all perfectly legal.
Personally I would want to see a weighbridge certificate before I would purchase any van...plenty have been caught out with an illegal , overweight van. Salesmen spin too much bullShit.
^^ This. Everything here is gold, right down to salesmen telling you what they want. They don't care if they sell you a van you can never legally tow!
We have spent MONTHS now researching what van we're buying (we're a little different for you - needs to be capable off-road and we can tow up to about 3.3 tonne comfortably, but aiming to keep to 3 tonne if we can). We have it down to a single brand of vans because we've nit-picked what we like and don't like about the different ones out there (suspension, frame, other build components, etc. etc.). It IS overwhelming when you first start, but you will find good information online. The Caravaners Forum is also a great place to get some advice. We've had some very sound advice (and some not so sound - you will need to be very discerning with what everyone tells you!) from guys on there.
- Don't forget GVM and towball weights
- Do you need to go as big as 23ft? Its amazing what can fit in a van 18-20ft if its just two people you're catering for, as long as its been well designed!
- If you are going to predominantly use it at caravan parks do you
need a washing machine? It is amazing what you decide isn't 100% necessary once you start thinking about weight and space considerations!
- Don't forget about kitchens - are you happy with something basic (a couple of burners, a sink, and maybe a microwave) or do you want a complete kitchen with an oven?
- Do you want an ensuite with separate shower and toilet, or is a shower over toilet OK? I was dead against the shower over toilet configuration, but once again decided I was being too fussy and it wasn't that big of a deal when it meant we could consider shorter, lighter vans if I compromised there.
The other huge considerations are budget and if you're planning to buy new or second-hand.
Oh, there's also apparently a Lemon Caravans Facebook group. My husband loves it (I'm not on Facebook so I'll take his word for it!). He's found out all sorts of gems from there, like certain caravan brands going into financial troubles when they tried the hard sell on us only perhaps 2 months ago.
Good thing we didn't like their vans anyway.
The other thing I'd recommend doing is going to a few caravan shows. Have a look at the build quality (we were shocked at things like poor quality joinery and all sorts of other things), talk to the salesmen. Be very, very wary. Salesmen will feed you a lot of rubbish and expect you to be dumb enough to believe every word (some of the lies we were spun were ridiculous!). Smile, nod, and get the hell outta there. If the vans on show have faults or their salesmen are telling you blatant lies, what can you expect if you actually went ahead and had a van built through them?!
