We did this mental dance about 6-12 months ago. Looking at NL 9-6 sportsman or Hallmark cuchara as our camper choices. We were going with a new truck and probably used camper due to costs. We live in CO and the primary use was to be skiing trips, ice fishing in CO and then longer summer road trips with a family of 5.
Our choice:
2022 F350 CCLB (gotta fit 3 kiddos)
7.3l, 10 SPDR, 3.73 gears
Dual alternators, dual battery, upfitter switches, rear sliding window, remote start, sync 3
While the 3.73 didn't give us the max payload that is available with the 4.30 (11500 vs 11900) we wanted to get a little better MPG and were not super worried about racing up highways or MTN passes.
Camper: Originally wanted a NL for the extra storage space inside and insulation properties but after viewing the NL and a Hallmark Cuchara we settled on the Hallmark. It has less fixed storage but feels more spacious to us due to the lack of fully built up cabinets. With 5 people it is tight in either camper however the Hallmark felt less crowded and we were able to get the over dinette bunk bed.
We have camped 4 weekend trips and a dozen day trips since we put the setup together in November 2021. It is always on the truck which is great. So when we go to the lake for a day of ice fishing there is always a second area to relax if you dont want to be in the fishing tent. When we go skiing this becomes our our lunch area and a place for movies when the kids are tired from skiing. It is a large setup for a truck but fits in most lots and is not a bear to drive around town.
The 7.3 handles the camper with ease. We get about 10mpg in the city and about 13.5 mpg HWY with and average trip mpg of 12.5-13 depending on our conditions. The lower profile of the Hallmark makes a huge difference I believe with winds, both front and side, and is rarely felt. With the intent of hauling a TC as a primary purpose I would go 7.3l and not look back.
When lookin at trucks the markup for lot models was crazy with either new or used. I refused to pay more than MSRP. I happened upon a dealer in Iowa that was doing 2% under invoice.... yes, under invoice. Ordered the truck exactly the way I wanted and saved 4-6k vs local dealer ordering it and probably 15k+ over buying something off the lot.
