We have a caravan and an ex-army number 5 trailers - I have a different hitch for each one to tow level.
Personally, I would not change the ride height for long distance driving. As stated, the increase would raise your center of gravity.
I dont use the useless land rover hitch - mine is a mitch hitch look alike, similar to this one.
Mitch hitch are now out of business, so you need to look at other brands here in Oz. I think 4wheel drive industries also have an approved one.
