What Dion said. The only way to make it different is if one vehicle is using an equalising strap, then half the load is placed on each of the two recovery points.
Off-centre pulls increase the risk of damage - force vectors are not straight down the chassis. Steel is excellent in tension, good in compression but it's malleable - meaning it will bend easily, stretch less easily - a straight pull will stretch, a off-centre pull will bend, and that's your chassis too. Equalising straps can be used to reduce the risk.
(The whole reason why they use steel inside concrete for construction is BECAUSE steel is so good in tension - it holds the concrete together. Concrete is excellent in compression, but hopeless in tension - it will crack readily if you pull it apart. Put the two together and you've got a structural member that is greater than the sum of its parts. Hence our bridge spans are pre-stressed - stretched steel with concrete poured over it and allowed to set - or post-stressed - conduits over which concrete is poured, allowed to set and then steel cables are tensioned up once the concrete is dry).
