I should imagine everyone would have a lorry if they could afford to keep one on the road! We have a trailer for simple economic reasons, although the advantage is that a 4x4 with trailer is less likely to get bogged down in the fields that pass themselves off as car parks than a lorry.
<span style="colorurple">I've got a trailer as cheap and easy! Would much prefer a lorry though and I could drive that instead of relying on my yard partners dad and brother. </span>
Currently have a lorry and love the space etc but from a cost point of view much preferred the trailer towed by my OH's company car, no insurance and fuel costs.
