Something to look out for, grade 3 bolts.
The lag bolts that hold the generator to its axle were grade 3, aka grade A, A307 and free spinning nuts. Don't use the grade 3 for anything other than holding down a trailer deck.
I tried to find grade 5, but no one had them in 5/16 so I just went with stainless lag bolts and I have some stainless steel lock nuts. Due to the high alloy content stainless bolts can be assumed to be at least grade 5.
I have found grade 3 bolts in load bearing applications will randomly fail.
With a 400lb generator with 13 gallons of gas going 70mph down the road you don't want it coming off the trailer.
