We looked at a truck with a running board and I still found it difficult to hoist myself up into the seat - the 3/4 tons are all so tall and I am short -5' 3". We bought a little step stool but haven't been back to try it out yet - will the end of this week. Just seems like that would be a hassle every time I get in and out but might be necessary. However, the main point is how well a truck will tow for the type of travel we will be doing. I think we have narrowed it down to a Ford or Chevy. The RAM trucks are great but the seating is just not comfortable enough for long term travel.
The wife and I had the same issue. She thought she wanted a 2500 Ram and being 5' 2" and 75 years old the dealer had to use steps for her to get in the seat. The killer was the ride. Now I have a 2500 Dodge/Cummins quad cab and a 3500 drw crew cab chevy and both rode one heck of a lot easier than the new 2500 Ram/6.4 Hemi crew cab.
So she settled on a 1500 chevy 4wd 5.3 crew cab short bed 6 speed tranny 6.42 gears with side tube steps. It does a good job pulling a 10k car hauler with 9460 lbs on the trailers axles but 6-7k trailer would be a piece of cake. The new 1500 chevies now use the 10 speed tranny. Those that have them say their superior to the 6 speed trannies.
If you go with a F150 be aware they have different GVWR/RAWR packages and all can come with the same engines options and the "max tow" option.
#1. 7850 gvwr...4800 rawr....2500 lb in the bed payloads.
#2. 7600 gvwr...4550 rawr... 2200 lb in the bed payloads
#3. 7050 gvwr...4050 rawr... 1800 lb in the bed payloads
#4. 6800 gvwr...3800 rawr...1500 lb in the bed payloads.
#4 may be a bit close on payload.
# 3 on up would be a good choice.
