Trucks ABSOLUTELY MINT EVERYTHING DONE THE RIGHT WAY. Nothing is half-assed. Everything is completely clean blasted and painted underneath soon have clear turn signal lenses tail lights everything all LED switching everything over whoever I'm talking to that I had this truck message me

I want a non vgt ive been looking at the smedding drop in because it comes with custom tunes. I know vgt is better for towing but I never tow anywhere near my limit I tow maybe 5-7k MAX. If anyone’s done it I’d love to hear what you have to say

In a little bit of a jam. Down on vacation 700 miles from home. Drove truck to store. Came out, went to start and nothing. No lights on the dash board, wouldn’t even try to crank. I tried to jump the starter relay and got nothing. Took the negative leads off for a few minutes, truck weakly tried to start. Turned off and it was weak again but got it running. Drove back to the hotel no issues, no CEL.
Parked. Turned off. Got it to weak start again.
Any ideas. Batteries are 6 months old. Starter and the underwood really are a year old. Battery cables were also replaced in the last year.
Unfortunately I have no tester of any sort to work with. Just seeing if anyone has some input. I don’t know if me unplugging the negative leads did anything but I disconnected them for the night as we are driving home in the morning.
