Having had a couple trucks as tow vehicles, and having had the fiberglass shells on both trucks leak and get our gear wet in downpours, we have opted for a full sized RV. Just before that 9900 mile Mexico trip, we got a recent year Ford Expedition 4x4, which is a F150 based SUV, with the Ecoboost 3.5L and 10 speed transmission, as a 2019, it has some engineering improvements over the first gen ecoboost and stuff. Its not perfect, but damn, it was comfortable for that 9900 mile 4 month road trip. Towed the 4500 lb E21 like a dream over all sorts of rough roads. After getting home from that trip, I did get an Andersen WDH hitch because we did feel a little tendency to sway and pitch once in awhile, and the Anderson on our first trip after getting it completely eliminated any of that.
The Expedition 4x4 (not Max) turns in a 42 foot circle, I have to be a little careful not to clip a taillight doing a really tight circle. My tow vehicle for this E21 for most of the years we've owned it was a 2002 F250 4x4 diesel 8' long bed monster truck, that thing had a 62 foot circle, which made tight maneuvers really difficult.
If you prefer chevy, a late model Tahoe would be the equivalent of the Expedition (not Max). or if you prefer the long wheel base, then its a Suburban vs a Expedition Max.. I wanted to be able to parallel park in a normal sized parking space so I got the short version, its still a 3 row SUV with 8 adult seats, its just shy on cargo space if the 3rd row is deployed.
Since there's just two of us, heh, cargo space?
