Thanks in advance for any advice.
so now you've got 3 threads on the SAME vehicle and trailer combo?
seldon is doing that wise, but don't let that discourage ASKING questions...
questions is good!
bouncing around means incomplete info about the primary issues/background/components and so on...
which only brings incomplete answers and advice and may actually produce BAD suggestions from the lack of details.
it might SEEM useful to split hairs on towing issues, but the needs HERE are all basic and interrelated to ONE combo.
-truck battery has no impact on trailer, the alternator does but ONLY if the demands to power/charging via the 7 pin are excessive.
and shouldn't be with a factory stock single deep cycle, single axle NEW trailer.
-the "upgraded shocks" and more BEEF issue has been addressed in the other thread.
-use the fuel spec'd in the owners manual which is largely based on COMPRESSION ratings for the 4 banger...
SOME high compression 4s spec high octane fuel and using LESSer fuels will result in lower performance in those engines...
most MODERN engines will just adjust/dial back the timing for that fuel, which is harmless short term, but lowers mpg OR hp or both.
LONG TERM use of higher octane fuel than required has NO real/measurable benefits...
since the engines that SPEC 87 have no mechanism for advancing the timing or increasing compression.
modern 7 pins are all identical on USA spec'd 'stream.
some (most) auto makers have pre-made wiring harnesses that can be added as part of a "towing package"
check with a toy' parts vendor for a specific harness for this 02,
there is NO reason to fabricate one, OR use a generic towing harness IF toy' parts suppliers make a version for this truck.
