I have a 1990 f250 4x4 zf5speed 7.3 non turbo with 4.10 gears. I have a 18ft travel trailer and I'm upgrading to a 28ft one. My question is can the pull it up grades? The EGTS get pretty high just on the highway with the 18ft. I just don't want to over do it.

Keep it under 1100 and you should be OK.

Turbo would help. Had a nice drop in EGT's with the addition of Moose turbo from Conestoga Diesel Injection. Made a good difference in towing with the 'ol 6.9. It took quite a bit of fabrication though.

What is the weight difference between the two campers?

My IDI likes RPM when climbing a grade with a load. If I don't keep the RPM around 2500-3000 the EGT's start to go up quickly, which makes the oil temp rise, and finally causes high coolant temps.

I have no clue what my old ones weighs I know the 28ft is about 5600 empty.

I think my dry weight is about what you mentioned. I get up the hill just fine but I’m not NA with a stock pump. I concur with what Heath said although my experience has been having water temp issues not egt problems even with the bull moose and similar turbo to what Heath is running. NA you won’t be racing anyone up the mountains.

She'll always do it, the question is how fast. You can always slow down, drop it a gear and keep the throttle just below your EGT limit... but you might be going 25mph in 2nd.

With a turbo and fueling, you can go a lot faster; cooling does become an issue, and it's one of those problems where if you slow down, you get less air flow, things get hotter, slow down, etc.

If you can find one, a Banks Sidewinder(wastegated) turbo is a really good match for a 'stock' 7.3 - one with a stock-sized(but maxed out) IP and no headstuds). Unplugging the wastegate on one will net you 14-16 psi, 200-220rwhp(about double N/A levels), which is pretty close to the maximum you want to run without studs, and also enough for the maxed stock IP.
R&D stage 1 injectors also seem to do well in this setup, but arem't required or anything.

So the camper I ended up buying weighs 8600 dry. It seemed fine pulling it to my house but it seems like a lot of weight for it.

I don't plan on racing up hills as long as it will make it there and back I'm fine with it. That's a nice looking pickup.

I'll keep my eye out for a turbo for it. Hopefully I can find one here soon.

I am towing a nearly 10,000 pound RV, our full-time home. I started with our 90 7.3 NA F250. To say that it was a tedious PIA to pull through the mountains is an understatement! I added the ATS turbo kit from typ4 (Russ) w/upgraded wheel, baby moose/ moose mate injectors, Banks downpipe and a 4in exhaust. The difference is astounding! Although I do have to watch the temps and sometimes drive by EGT when going through mountain passes or on long steep climbs, I have enough power to comfortably get through the mountains. Add a turbo kit run 10 to 12 PSI, don't exceed 1000 degrees( staying conservative on both the Boost and temperature) and you're good to go. It's like night and day...

Yeah I figured having something that weighs 8600 dry was going to be a lot for it on the hills.
