2 wheel drive or 4 wheel drive

If your just pulling a camper around on pavement you don't need 4wd. I use my trucks for lots of other things and need 4wd quite frequently. I made the mistake of buying a 2wd work truck once and that was enough.
Around here you can't hardly give a 2wd truck away. But, here it snows and there are lots of mountains. Maybe that's not the case where you live.

One thing to consider is the height. Depending on your hitch and tongue height of your trailer, the 4x4 may require you to raise the trailer to get the proper bed clearance. For example, I had to flip the axles on my trailer to get it to the proper height. Some trailers have adjustment in the shackles. Mine didn't. I live in SoCal and rarely leave the road. There was at least one time where my truck would have needed a tow to get out. I had to go up a loose gravel driveway in the June Lake area (trailer not attached). I couldn't get any traction at all until I put it in 4WD. Then it was like I was on pavement. As mentioned, 4LO is great when doing parking maneuvers. You don't have to rev as high in 4LO to get things moving which saves on the transmission too with less slippage (=heat)with low speed maneuvers.

Depends on your style of camping. We use 4WD frequently. We like to travel backroads and see thing that 99% of travelers will never see like this for example:



Cathedral Valley road near Capitol Reef

or this:



House Rock road near the North Rim

If you are happy being shoulder to shoulder in the crowd looking at the same sights that everyone else sees then you don't need 4WD

Had both. Don't miss the 4X4 one bit. My dually may not have the traction, but then again I am not going to put a 13,000+ fifth wheel on wet grass or dirt, so why do I want to pay a premium for it?

What kind of places do you go camping?
Have you needed 4WD in the past camping?
Are your camping plans changing?

Only you can decide if you need it or want it....

I only needed it once in 7yrs of FTng due to wet grass...and I really didn't need it....what I really needed was to swap OEM highway thread tires out for a better gripping tire.

Regardless of 2WD or 4WD.....it is going to be a 'dually' correct?

You're on pavement all the time, probably don't need. Pull thru or back into level campsites all the time, probably don't need it. You're not, good to have.

Parking your RV using 4 low on steep grades is very nice! Also pulling one side up on thick blocks when the site is sloped. Resale for sure!

I never needed one, but then again I stay on paved roads and don't dry camp. Roughing it is electricity and water only.

The resale is worth it alone. In this area anyway.

You don't need 4 wheel until you need it!!!! Then you'll wish you had it!!!!
