Correct me if ...I am WRONG here... :?: 
The 
BIG truck...debates..have little to do about the EQUIPMENT....
But ..more about the "Box truck"...VERSUSES..the "Van"... :idea: 
I have operated the 
AT & the 
Vortex...There is NO DOUBT..their power is
superior to any SLIDE-IN.. :!: 
We run ..ONLY box trucks..!!! We also have the LARGEST slide-in's on the
market..! But we run these units...because of the LARGE exposure that our 
"WRAP'S" provide for advertising..!
We also can carry "ALL" the equipment necessary to perform whatever the client
needs to have cleaned..THERE & THEN"! These trucks carry the weight BETTER...
Separates the men from a SMOKING HOT..machine & chemical & exhaust fumes...!
These DIESEL motors carry a 100,000 miles "No questions ASKED warranty"...
They also provide enough ROOM to service the equipment & clean the truck easier.!
HELL in Most situations...you can purchase a BOX truck cheaper than a VAN... :shock: 
And they hold their RESALE value ...much better than a "2year old RUSTED-OUT..Van.:roll: 
QUESTION..???
Are you more likely to pay more to a Company that bring's a BACKHOE to your 
home to dig your new pool..."IN 1 DAY" :?: 
Or pay the another Company that brings 5 guys with "SHOVEL'S"... :?: 
They both can get the "JOB" done... :!:  It is just the guy's with the "shovels" will
be there for " 3 WEEKS"... :roll:
