Hi
@IIISAMIII and welcome.
This is very subjective, but here's my take (others may disagree):
- The 102bhp engine is adequate, but I wouldn't recommend it for a full camper conversion, carrying heavy loads or for use in particularly hilly areas,
- The 150bhp engine provides all the power you'd need, including for campers, heavy loads and on steep hills.
- The 199/204bhp engine provides all the power you'd want and is very responsive in just about all situations (for a van), with only a small hit on mpg,
If money were no object, I'd have gone for the 199, but money was a constraining factor for me, so I went for the 150 and spent more on options instead.
As for short runs, I guess you're alluding to DPF issues. If the engine regularly isn't getting up up to temperature, or you're constantly in stop/start traffic, then this can cause issues with regen. There are, however, steps you can take to minimise this. These include using premium diesel, using a diesel additive, using high quality oil and changing it regularly (every 10k), and taking the van for a long run periodically. I'm no expert in this field, but there's lots of info on this forum if you look (use the search function top-right).
Happy reading!
