We will take our long awaited journey next week across the US. I would like to ask for some pointers towing our 4500 lb jeep behind our 36 ft. gas ( 2003 workhorse chassis ) Motor home . How hard are the Mountains out west with a towed vehicle ? Rockies I 70 and norther California and I 80

Thanks in advance sj

For the most part, you'll not even know it's back there, but if you have a P30 chassis and a GM 4L80E tranny, you may experience some overheating of the tranny on long 6% grades and the weak link in your setup.
This being the case and with the tranny going into limp mode at 270F, just pull over and continue in low gear at 25mph. This will give you another 25% more or you may choose to disconnect and drive over the top separately.
If you have a W chassis, this potential problem disappears with having an Allison transmission.
