Streching a frame?

What are the pros vs cons about stretching a frame. Taking into consideration that the company stretching the truck know what they are doing. And that it is the cheapest option for you because you just need another 12".
Are there any companies that will not hire you on because your frame was chopped/stretched?
I received two quotes both around $4000.00 guaranteed to be lazered and true.
One wants to cut behind or below the sleeper and add plate there.

The other wants to place plate on the end and move all the hangers back.

which is the cleanest and best?

Thanks and stay safe

 

I do not want to buy a new truck, I do want a sleeper bigger then 63 to 70" and I want to put a headache rack on. I have looked at many trucks and the ones that fall within the weight, sleeper size, engine, and tanks are just to short. Rather then buy new to order, I could spend 2k to 4k and be done. I have stretched them just behind the birth but I was wondering if anyone had stretched one behind the axles and then moved the axle and 5th wheel accordingly, sounds like alot more work but I was wondering if anyone had experience with it being truer

 

IMHO???? behind the birth or between the axles or behind the axles

 

Yes, that is what has been told to me. Thanks for the info and confirmation!

 

We were looking at cutting in at the end of the suspension, just behind it, rolling it back and moving the 5th wheel back also. I assume that is what you were referring to.
