Installed a 2 gallon accumulator tank for sustained off-grid water pressure plus far less pump activation. Cheap tires replaced with Carlisle Trail HD's (U-Haul runs on their entire fleet, the most proven trailer tire by far). Added Sumo Springs and heavy duty shackles with "wet bolts" to ensure a smooth ride. Added Simcoe Springs 2" lift kit (a must for towing with a modern 4x4 to correct nose high towing and rear jacks too low). Dry weight of only 7920 lbs. with a pin weight of only 1473 lbs., for a true "half-ton towable" RV. It pulls so smoothly and at 29'11", it's easy to navigate.

MORyde Step Above entry steps adjust to the ground - very stable. Replaced entry door frosted glass with tinted glass and a built in drop-down shade. KoolRV adapter to quiet and maximize A/C. Rear camera was replaced with a HD camera and big viewing screen for the towing vehicle (like having a high def rear view mirror). Includes a Curt Rota-Flex cushioned pin box, however we tow using an Anderson Ultimate hitch, so the Rota-Flex pin box has been "locked off" and the inner rubber cushion is still new and unused. Tow package at the rear rated for 3000 lbs. and a hitch weight of 300 lbs. With the slides closed you still have access to the kitchen, bathroom, and bedroom. Includes a brand new microwave we removed to add the plate rack and dimmable accent lighting (now reinstalled). No smoking, no pets, and still smells and looks new inside and out. Tallest bedroom in mid-profile class (and no step-up). 4 seasons camping with heated underbelly and excellent insulation. $6500+ in post-sale upgrades.
