Some are gona hate me for this.
Your situation is a CARBON COPY of what I went thru two years ago and one month. Quotes of $ did not even come close. Our only difference is you have two trucks I did it with one. Same Carrier, same story.
You want to survive? Of course you do, find a different CARRIER TOMMOROW! As much as I respect others opinion here, you have not screwed up buying your own truck for yourself, but two now theres a problem, but I beleive with the right management you can not only survive but prosper. Where you are at now with those #s its only a matter of time if those trucks have loans attatched to them.
Now I hope, and you did not post this but you better have some savings to carry you into a change over as this is the key to survival in this business or any business is capitol to bridge you when things do not turn out as you planned. Did you do a business plan? This will help you in planning your course.
