2004 2500 555/5600 RWD QC/LB
At 15 mpg he must be driving very fast to need fuel every 3-4 hours.
80% capacity max range = 21-gallons. Agreed, @Jimmy N. 315 divided by 21 = 14.85. He’s averaging about 72-74.
Likely more a bladder thing (rest stops at two-hours a better plan; stay relaxed) as stepping down on throttle a side effect of discomfort. Stopping more often than he needs to given has no daily trip plan.
15’s my average across the flatter parts of the South with 35’ travel trailer (17k+ GCW). Why should I want an ED? (where GCW would be 15k or so). I’d have to leave out 1,200-lbs of gear permanently on-board, etc.
ED should be at 18+ (nice looking trailer. If a supported tarp could go from over front shield onto car hood that’d help)
To look at Fair Rate of Speed + Low Risk & High MPG Trip Plan:
At a 55-mph dispatch rate (higher than big trucks) where all trip hours are accounted (not just drive time), a hypothetical 2,088-mile trip Fort Worth to Charlotte, NC roundtrip is 38- hours.
(3.5) days of 600/miles daily pace inside an 11-hr drive time (12-14/hr trip time).
— Run at 74 doesn’t change drive time enough to matter given on-road penalties of IH-20 traffic volume (plus damned Atlanta twice) versus increased rate of fuel burn & vehicle component wear coupled to unacceptable risk.
There’s only so far one can go in a day. Over 3.5-days (four, to allow for problems) so look at the planning limits.
There’s not much open road that route versus twenty-five or thirty years ago.
If I want to run the KW “fast” I have to plan so as to get past Atlanta at the best hours (one-hour planned minimum penalty even at 0300) so as to keep daily & Trip Average MPH highest (correlates to best consistent fuel burn).
— Atlanta (like D/FW) its a window 0900-1300 to hit one side of the metro 75-miles out from city center and expect to make it across expeditiously. (Otherwise past 2300 till 0400).
Atlanta to Charlotte on IH-85 is one of the worst stretches of Interstate in the US for traffic.
The round-trip is going to take 3.5-4.0/days no matter at what speed I park the cruise control.
Wanna make time?
— Leave early & stop early. Repeat daily. 0400-1600 works (except Bos-Wash Corridor where it’s 0100-1300).
— Traffic volume (peaks nationally 1100-2100) will make or break any plan. Get the miles in early. Ask any truck driver about the importance of the first 4-5/hours on the road.
I was planning that trip — done many, many times — I’d use:
(East of Dallas, DUKES for BBQ and/or Rest Area MM 538 just to get out of town); then,
1). Petro at MM9 Shreveport, LA
2). Rest Area at MM 96 Choudrant
3). LOVES at MM15 Vicksburg, MS
4). Rest Area MM90 Forest, MS
5). T/A at MM77 Tuscaloosa, AL
6). Rest Area MM84
7). LOVES MM205 Heflin, AL
8). Petro MM160 Carnesville, GA
(An absolute point in my plans: E of ATL t’s Indian Territory all the way)
9). Rest Area MM2 Grover NC
Tuscaloosa to Carnesville = 261-miles (315-mile max towing range). That’s the leg where the stop points (uncrowded) are crucial. Day or Night.
It’s only 150-miles Carnesville to Charlotte.
300-mile roundtrip plus business (big truck it’s live unload and re-load). There’s the short day of the trip (back to same Petro; earliest departure to get past ATL in the dark).
— Otherwise space the rest area stops at about 2-hours to maintain alertness. 4.5-5/hrs for fuel.
This ain’t rocket science. But it pays cash money.
A). Plan the trip legs with addresses into GPS.
B). Execute each leg separately.
C). Have stop point as last.
MPG Penalty (assuming good plan) are the intervals off CC to exit and do business, then to re-enter Interstate. (From CC “Off” to CC “On”).
— The later the daily start the worse the discrepancy between CC set speed and actual average being made due to traffic volume.
A) It’s never legal to travel in the left lane of a US Interstate. It’s only for a single pass.
B). It’s flat illegal to block access to the passing lane.
C). Right-of-Way is to travel-lane only (right lane).
—,Short version of above is that if I need to come over and traffic is illegally traveling in the passing-only lane, is illegally tail-gating, and thereby illegally blocking lane access (ROW) . . .
. . I’ve no compunction about coming over to the passing lane — occupied or not — as it’s a near-certainty the crash that’s occurred ahead and is having a chain effect on drivers ahead of me who’ve failed to maintain separation distance adequate to the road, the weather and the traffic volume I’ll rear end at a high speed
If you’re in the left lane with three strikes already against you . . you don’t exist for what’s necessary at that point. (Same as operating without insurance though the other guys fault; it’s entirely you shouldn’t have been on the road at all).
— Moving to left lane the very best choice as to incurred liability. And, if you think I’ll sacrifice myself, guess again, as the law is also clear about that.
“Skill” cited will getcha laughed out of the room. The statistical spread between best and worst drivers on the planet is minuscule. It’s the roads, the laws and the conditions.
The conditional increase of less and less intelligent drivers plus those vaxxed have taken death & serious injury rates right now to their highest level in a decade (when cars & roads weren’t as good; with lower traffic volumes).
Being trapped against some big trucks with low-skill, non-heritage “Americans” or foreign drivers to the right, and then one is ahead & behind others of the same derivation = Can’t Fix Stupid.
It’s just not hard to have low-risk & high-mpg at a fair rate-of-speed to be all three the same thing as conditions dictate limits.
