I am a 2003 6.0L owner considering taking the plunge and going with 2006 or 2007 V-10. Living in Colorado, I ocasssionally tow over the passes. I am sure the 4.10 would do the job, but would 4.30 make it that much easier? Is there much of a difference in gas mileage between 4.10and 4.30?
I have an 05 V10 with 4.10s and am very happy, but I'm in the Sac Valley in Northern CA. I only have mountain passes when I go on vacation. From what I've read here on FTE I believe the consensus is that 4.30's give you more torque for working and playing and there isn't much of an affect on mileage. I'm sure someone with personal experience with 4.30 will be along soon to give you the scoop.
Oh and welcome to FTE. This is an excellent source for Ford truck info and the guys in the V10 forum are a good group.
The 05 and up have larger wheels than the 99-04's. If you get the 18 or 20 inch wheels go with the 430's which is the about the same as the 17's with 4.10's, 33.2" for the 18's and 31.6" for the 17's. I have the 4.10's with the 17's and tow a fiver that weighs 17,500 combined with my truck. Cruises at 65 @ about 2,000 rpm all day in OD. Only kicks down for the hills. With you being at high altitiude I would say to go with the 430's. At 65mph with 18" tires you will be at 1920rpm with 4.10's and 2010rpm with the 4.30's. The same speed and 17" tires will put you at 2010rpm with 4.10's and 2110rpm with 4.30's. Gas mileage should be about the same from what I have seen on the board.
I just got a new 06 reg cab 4x4 with 410 gears do a lot of hauling hear in western n.c mind does very well pulling around hear you dont get down one mtn tell your going up another. i cant say about a 430 vs a 410 ive never hauled with one i think you would be happy with either one .
I had a 2000 with 3.73s and a 2001 with 4.30s, both trucks equipped the same.There was about 300 RPMs difference at the same speed and there wasn't any difference in gas mileage between the two. I'd get about 10 pulling our 28 ft 5th wheel, and 8.5 pulling our 20 ft cargo.
As an ex diesel owner I am happy with the 4.30's my 99 V10 came with. Seemed odd at first with all the rpm I had to play with but now it's just plain fun!

On the rim size statement, it's not true as a rule.
The rim size in itself means nothing.
The tire diameter is what matters.
A 20" rim tire can have the same tire dia as a 17" rim tire.
If the diameters are the same, nothing else matters except looks and typically lower load bearing capability of a larger rim/lower profile tire combo and the lower profile tire will have worse ride quality.
All that aside, I have the 3v with 4.10 and they are great. For the hills, 4.30 wouldn't hurt anything.
I average 10 mpg towing an enclose car hauler with a total weight of at least 8k. If I towed a bit more weight, I think I'd like the 4.30 better going over the mountains. For my current 5k foot alt hills, the 4.10 towing 8k is fine.
Lower weights and or not many hills, go 4.10 for the milage
Higher weights and or lots of hills, go 4.30 for the grunt and probably not much worse milage if any loss.
I have a 99 V-10 with 33" tires and I really felt a difference switching from 3.73 to 4.10. When I use my factory 31.7" tires the 4.10's really make it go. Gears and the banks power pack!

That is why I gave the diameters afterwards, I was refering to stock wheels and tires. He was looking at purchasing a new unit. A truck with the stock 17's and 4.10's will turn almost the exact same rpm as a truck with stock 18's and 4.30's.
