Ok so 3 months ago I got this idea to try and save some fuel on a daily basis. Well i did not want to sell my trucks and get smaller ones, nor did I want to go throwing a lot of money in 10 different directions trying to figure it out. With that in mind I took one of my 8x12 trailers off the road and replaced it with a 8x5 . It took some trial and error but we got a ZTR and 32in WB 2 fs80, 2 fc75's 2 BR600's a 5 gallon fuel can a 2.5 gallon fuel can 5 pound spool of trimmer line on it. Well the 3 month results are in, looking at a 7% decrease in fuel consumption on that truck vs the twin of it with the larger trailer. Never once did my crew not have what they needed, or did they jack knife it backing up do to shorter wheel base. It took them 2 days to get use to the smaller trailer, but now they said the like it much better then the larger one. So looks like were gonna run the 5x8 trailers as our res rigs and sell the 12 footers off. We still use a 16 footer for my commercial crew as they carry so much more equipment. So is that big trailer worth the extra fuel you burn every year?
