Hi, First post. I'm getting my 5th wheel (Sun Valley Extreme Lite) in a few weeks time and get my Nissan Navara later this week. Can anyone assist by pointing me in the direction of a fair-priced hitch installer? Calder Leisure quoted me £1200. I thought this was excessive. I'm in Scotland but would drive a reasonable distance for a decent saving. Would it be better buying the kit separately and trying to get it installed by enginners/electricians? Thanks in advance.
