Hi,
We own a 2016 Sprinter Crew Van that we have converted to a travel van. We have a Dometic 15,000 btu Brisk Air II, 4.0 kw Cummins Onan generator, pure sine wave inverter. We created storage in the back by raising the standard u shaped seating/bed (74" x 69") up 16" so there is storage under the seats, in both boxes of the seat and a huge storage area in the back. We put in and take out the bench seat that comes standard with the crew van as needs dictate. We put sound proofing and insulation everywhere, mounted a 40" Samsung hi def tv, focal speakers everywhere, Pioneer Avic 6200 receiver, flooring and wall covering. We started seriously driving the Sprinter, our LLM, in May 2017. We have traveled cross country twice and now have 45,000 miles of mixed highway and city driving. We have averaged 20.2 mpg overall. On the open road with cruise control on the flatter sections, driving 65 mph, we have averaged as high as 26 mpg; though more normally 23 mpg.
One of the best items purchased for the LLM is Verizon HumX. For the price of an additional line on our wireless account, our LLM is internet capable. TMobile has their version also (SyncUp), though we had mixed results with their wireless capabilities (for both phone and internet) from Ft Worth, TX to Little Rock, AR, to Nashville, TN to Lexington, KY to Ithaca, NY. No problems with the Verizon system, though I believe the TMobile SyncUp has more capabilities.
Per many of your recommendations, we upgraded to Koni struts and shocks and a larger Hellwig anti sway bar. We still have some bounce in the back. I am not interested in spending the $8200-$10,500 for a VR or Glide Rite air bag system. However, I have been told that if I change the springs in the back to a 4 or 7 leaf spring configuration, my ride will dramatically improve. Has anyone done this with the improved results that have been presented to me?
Thanks again for such a wonderful website.
