If you can then go for a 130 or 174. They are both the 5 cylinder engine with no belts to change ever! All gear driven cams so that will result in a big saving over time.
I have a t32 lwb 174 kombi. Even loaded right up it will overtake in 5th no bother. Its 7 years old now with 85k and when I had a service the new transporter they lent me felt no better than mine. It drives like a car. I have a tailgate rather than rear doors and that's useful for keeping dry when loading/ unloading. Had transits for 18 years prior to this and although I found them virtually faultless, I would rather have a 2nd hand vw t5 than a new transit for the same money.
Get a t30 or t32 and it will handle better with the weight. The t32 has bigger steel wheels due to bigger front discs and rear discs instead of drums.
