so i'm looking at around 1000 pounds filled up, i've had a bit more weight than that in the back of this truck and it was fine, if i feel its necessary i may beef up suspension. braking was never an issue with that weight. but 50 gallons of liquid sloshing around is probally alot different than bags of fert..
i was gonna start out spraying my lawns at 2 gallon per minute rate, i've never sprayed lower than this, aren't the blue tips for a 1.5 rate??? i've always seen good results from 2 gallon rate, but never gone lower than that.
