Yes, pretty big by our standards. Our options are all mid sized and usually with small diesel engines, like Nissan Frontier but called Narava here.
I find the LHD a bit easier actually, I seem to be able to tuck much closer to the kerb and judge the white line. Sat high up so visibility good but you do have to choose your overtaking moments. Ram will be a bit smaller than the Raptor so should be fine. Parking spaces are small, so best to avoid shopping at busy times and park miles away to avoid door dings.
Blind spot detection did save me from wiping out a MX5 when changing lanes on a highway, so I've opted for that again. I keep eye on rear view mirror way ahead of manoeuvres and give a bit of signalling time too just in case. The MX5 had got along side without me seeing him, just as I signalled I saw the blind spot flashing, he soon shot forward when he saw me indicate.
Only ever really had one spot of bother for size, I went to a coastal place I'd not been before and followed directions for a car park, lovely spot but I had quite a job to get it over a single track bridge with nearly 90 degree entrance and exit. I managed it fine in both directions - it seemed a better option than reversing about half a mile back up the road! It was a small bridge and wouldn't have been totally straight forward in a large car.
