Last time I checke DAP had the best price on rv's. Vulcan perfprmance a close second. As far as the cros over tubes, if you cant see or feel and damage on them I cant see why you would need to replace them. The steel they are made of is so freaking har it is rediculous. I chucked one of mine in a drill and spun it to polish the tip(maybe out of ignorance, I dont know)and it did not leave a mark on it. It is in the truck right now. You should definately change out the o rings on them. The biggest mistake I made was tightening the injectors before the injector lines. They all leaked. I had to take it all back loose and tighten the injector LINES first and then the injectors second. this stopped all the leakage I had due to them not being properly aligned. Tightening the injector tubes first aligned them properly. RV's versus 100's is beyond my knowledge though and some one else will have to advise you. They work grat in my truck.

If your just after mpg stick with rv275 and a small timing box like powerpuck. Will generally pick up 2-3mpg

for injector pricing, also check with Dave @ DB Truck Customs (facebook: http://www.facebook.com/db.truckcustoms) or RamHunter9 on here/RamForum.com

I got my rv's at FarmBoy Diesel. Paid $295 a year ago and the ride was included and no core required.

gonna max out tire pressure and empty the bed out see if i cant get the mpgs up a little

No need to do that... All you do is ruin the tires and ruin the ride. On a empty truck 50-60 PSI is more than enough.

ive been watching DAP site for their rv275's and still waiting for them to get them in stock. I called and asked how they can sell them so cheap, after they get the cores they refund $100 back to you and they take the cores, rebuild them and make the money off of them. These were for brand new genuine bosch rv275's and that was enough for me to wait. $500+ for a set when i can get them for half that... no brainer.
