I also tow in 5th gear at 63-65 mph in tow/haul in manual on cruise. at about 1900 rpm. The sweet spot for efficiency on the LBZ is 2000-2300 rpm. 6th gr is to low at about 15-1600 rpm and 4th gr is to high. It was worth 1.5-2 mpg increase in mileage. I also tow on an 80 hp tune.View attachment 1076013 View attachment 1076013
I have a 2020 Grand Design reflection 337rls fully loaded out the way it is just shy a 14000 lb. I tow it what's my 07 GMC Sierra classic 2500 HD Duramax Allison. Last trip was pretty flat and I got just over 13 miles per gallon. Don't have to worry Def has my LBZ 07 Classic didn't use Def.
Looks like you have 6", that's should be good. You don't want to jack the nose of the trailer up higher than necessary, better to keep it down out of the airflow as much as possible. Probably the only thing you need to watch is going over a severe hump while turning. But I've done that with a similar size trailer and a similar gap and never had interference.Just went and picked up our first camper. Got a really good deal on it. My question for you guys, how much space do u typically want between the top of the pick up box and the bottom side of the camper? I bought a used 5th wheel hitch and just threw it in. Looks like I have one more hole for adjustment to lift up and a few for moving It down. To me it looks like I should have more room but with this being the first camper pulled im not sure.
Also does anyone use the 3rd brake light camera? thinking that would be nice to have for hooking up.
Thanks for the input.
