Trailertrash --- Just downloaded the Tacoma brochure from the website. Impressive. Looks good, but, I haven't been in one to 'test the bed'. I have the Fleetwood Niagara, with the two king size bunks (memory foam topper and heated mattress pads), and all the same features/amenities the Tacoma lists. The refrigerator size is a smidget larger on the Tacoma (4.2 c/f) than the 3.7 cf of my Niagara.
But as to amenities, the bathroom is very nice as is the twin bowl sink. The freezing compartment in the 3-way fridge is great - will freeze ice cubes overnight and keeps ice cream also. The Furance (16,000btu) does a great job at heating (but you will use propane). The range/oven is very nice and works well (easy to clean, use). One nice thing about the Highlander series is the amount of counter space in the kitchen - enough for food preparation and/or set up of appliances/dishdrainer, etc. The 6 gal. auto ignition water heater is a good feature! If you were to purchase this model, I would suggest the addition of a Carrier Air-V airconditioner as it does a wonderful job of cooling.
The only disadvantage I can see to this unit is the lack of floor space....but, if it is only one or two people this might not be a drawback. The dinette is rather tiny, but again would suffice for one or two people. I did not notice whether the sitting area had 120-v outlets within easy access (if one wanted a table lamp for reading, etc., or where to put a television). There appears to be a little ledge on the back of the sitting area (under the window).
If you have the opportunity to view this model, I would advise doing so. Sit on the potty, cook a meal, lay on the bed - see if it all agrees with you. Remember to simulate being stuck inside for fowl weather for hours -- are the quarters cramped?
Not knowing if you have kids (if you do, this unit might not be for you due to floor space).....
I never thought about 'security' .... and never had any issues in all my years of tent camping or in the PUP. And, I don't know if the Tacoma and it's 'hard sides' are any safer than the canvas of other pop up campers in bear country. If you were to get this model, I would also suggest you invest in an awning and add-a-room (if available) as you will want the additional space (7x14).
Happy pup hunting!
