So far I have only been able to load 3 machines at a time on my truck. Last weekend I made a bed extention for my truck out of 3/4" plywood and some 2x4s.
The 2x4s help distribute the weight of the machines in the rear.
Got 4 machines on... could have done 5, but we were coming back for 3 more anyway. Plus it would have been difficult to unload 5 machines when we got to our destination.
New Record!!! Four machines at one time... let's try for 5 next time!!!
We came back for 3 more, it's nice to be able to line them up 3 in a row...
