It's my understanding that to get close to a 3,000lb payload in an F150 one has to choose the "Payload Package" and (someone can correct me if I'm wrong) it's only available in the bottom tier XL model. They also restrict the other optional goodies/packages you can tack onto the order. One has to step up to the XLT trim or higher to get many features. I've owned a 2017 F150 XLT Crew Cab 4x4 for 5+ years (1,761# payload) but priced out a factory order 2021 SuperCab with the Payload Pkg, as I was toying with getting a light weight truck camper. I dealt with the commercial sales guy at one of the local dealers, as he knew what he was talking about. At least for the 2021 models, I was basically out of luck as far as adding in some features I desired. I was poking around on the Ford truck build website the other day and this still seems to be the case. I've been extremely happy with my F150 with the 3.5L Ecoboost. At times I tow a 23ft "vintage" Airstream with it with a gross weight of 5,200 lbs. If I load the trailer up with fluids, food and gear and the truck bed with some bikes, firewood, generator and extra water if boon docking, I've frequently hit the max payload of the truck. This includes the wife and an 80# dog.
I don't have any interest whatsoever in a trailer with a dry weight of 7,000+ lbs. Granted, I'm not full timing, but even aside from that. Too ample for my needs. My interests are for something that won't self destruct on NFS & BLM roads including the primary unpaved but relatively maintained ones as well as their offshoots but not "jeep" trails". Also don't need a huge portion of what they are loading them up with, which only serves to drive up the weight and cost.
For those of us after the larger, four wheel off road trailers, the objective is usually to just be able to get past those last few difficult arroyos and washed out spots that would stop just about everyone else so we can boondock for extended periods of time in quiet, private spots. As a fulltimer, that's your primary goal, not rock crawling or overlanding like most of the folks here like to do on vacations and weekends.
I've yet to find anything that motivates me to shell out the $$'s they are asking now days. Quality generally sucks. A replacement for the trailer I currently have needs to be put together better than most of what is out there. My interests include a moderate to smaller sized trailer one can stand up in with inside cooking capability, internal shower, cassette toilet is adequate, queen width bed, internal storage for clothes and misc. It does not need to look like a house inside. Also, prefer propane heat, cooking and refrigeration vs having to rely on expensive lithium batteries & solar when off grid. The propane has served me well over the past 25 years. I do own a portable 140w solar panel that I've used with our current RV. However, I'm not trying to power all the appliances with it. Of course, electric is the way the RV industry is moving. As for weight 5,000 - 6,000 gross max, lighter is better. I've seen both the Escape and the Olivers up close more than once. While an improvement over most of what is out there, neither excites me due to cost/layout and, for the Oliver, cost. So far, one of the only ones that has caught my interest (that I discovered via this forum) is the Kingdom Camping Trailer. However, given that they are located in Indiana, I've not been excited to take a 2,000+ mile trip to see one. Won't purchase sight unseen.
