I hear that. Looks like in the future we may tow a loaded horse trailer, where the torque of the diesel would make that a breeze. But we're never going to be towing more than adventuring so I'll deal with slogging up mountain grades when towing, in exchange for the simplicity of the petrol V8.
OVE HBE is by far the best 4season poptop camper out there IMHO. Aterra has thinner wall construction, but has no poptop, so it can be debated which is more 4seasonable; both having Truma propane heaters.
Aterra is brilliantly designed with the use of space. So happy to hear you love your Wrappon. The dinette placement isn't ideal for doing bizness, but the only change to ATO's arrangement I'd like to have seen would be a slide-out Wrappon (into the entry way) from under the curbside dinette seat. Put the shower pan/drain embedded in the entry way floor, hang a shower curtain from the ceiling above the entry, use the entry as the potti room or shower room (*only issue with this is that you'd then have the drain for the interior shower pissing all over your entry steps, vs currently pissing out the rear lower of the camper).
In the HBE, that entry cabinet being used for either storage or half-high potti room makes sense, as where else would you put a potti in an HBE? (I'm glad they revised their shower pan in the dinette floor, so the interior shower is now usable for HBE'ers).
Weights; have a look at post 21 as I just revised the info;

Quick skinny;
-Latest weigh-in #3; 8550lbs w/ Buckstop bumper/winch/Baja lights, full 60gal tank, HPI crossframe/flatbed bare, gears/locker in boxes in rear seat area, some smaller Carli susp boxes in crossframe, me and dogs on platform (4900F/3650R). HPI's estimate to me was that total weight would be in the 900# range; flatbed ~500lbs, crossframe ~200lbs, underbody boxes 40-50lbs/ea. I'm unsure how much the stock aluminum truck bed weighs, and I don't know how I picked up 300lbs of F axle weight compared to weigh-in #2.
Camper wet is ~1250lbs.
So 8550lbs + 1250lbs camper + 200lbs 4underbed boxes = 10,000lbs with camper and 4 empty underbody boxes. Doesn't include any extra weight from Carli susp components, extra weight of 5qty 37" tires, 1 passenger, our recovery gear, camping gear, food, possible future short roof rack and 2 cargo boxes, etc etc etc. GVWR is 10,900lbs, so I'm going to be over that, even when being mindful of weights.
