On the gas tank, I have a 38 gallon tank so I feel good there.
That should give me a 500+ mile range on the highway and I will need coffee more often than I will need gas with that range.
Hallmark campers are impressive, just pricey. Have been surfing CL thinking perhaps a used Hallmark (even if it is needs refurbishing) might be a good idea. Also went out and looked at the Northstar website last night. There is a Northstar dealer not far from the Hallmark place so we may take a road trip up there and look at both of them some Saturday.
The next RV show is the big one at the Stock Show complex the first weekend in March, we will definitely go and see Hallmarks (and everything else).
I have a spiffy little 15 foot trailer at present. It is pretty cool but limited in where you can take it (obviously). However it is kind of nice to set up and plug in and then go do what you want.
I am still debating tires so the camper is a ways off yet.
