Looks like typically come in 4 and 10 ton varieties.

I'm usually fixing wrecked cars - straightening the front ends, etc, nothing major like frames, etc.

 

The 10 ton sounds like the way to go - but are those two big and bulky for using in tight places up front like the fender, radiator supports, etc?

Most of the time they aren't much bigger its just the hydraulic unit and hoses that are bigger. Would want to compare directly (like in person) if possible to be sure.
