Went through this process about 18 months ago now.......
......and test drove a few of them out there
My new daily driver had to be like a car when towing the caravan and grandchildren as passengers
And be a great workhorse towing the 3.5T Ifor and other trailers to/from jobs.
Got really good advice from James
@Shovelhands and bought a Nissan Navara Tekna new on a '68' plate back in November 2018

Opted for the Truckman top to keep my stuff out of sight from thieving bastards.
7 speed auto tows the Ifor well giving 24-26mpg when loaded. Always feels in control.
Seat covers used when on site and rear seat space used for welfare stuff

We even dragged the caravan down to the Great Dorset Steam Fair 2019.
Done just over 10,000 miles in the Navara and absolutely love it.
No troubles whatsoever so far.
Getting up to 47mpg solo at trunk road speeds. Bimbling around here getting just over 40mpg (shown on the dash)
As for getting the best deal, shop around and then get yer local dealer to 'price match'
We did just that - F J Chalke was recommend by James and we got a superb quote which was about £5,500 less that our local stealer

Then.......we test drove at the local dealers, in Colchester and made friends with the salesman.
We then negotiated a 'price match deal' within a few pounds of the F J Chalke offer
