Welcome to the Forum!
Quality: Most RV are built to the same low quality standard, using components from the same suppliers. The industry is VERY price competitive, so if one is less expensive, there is a reason!
The MOST IMPORTANT quality is FLOOR PLAN! I suggest a floor plan that is not just okay, but one you absolutely LOVE.
Tow Vehicle (TV) choice is a completely different topic. I have not googled your camper choices, so I can not make specific comments. However, if you need something bigger than a ? ton truck, seriously consider a 1 ton truck. Within a family, the ? ton and 1 ton SRW are essentially identical except for suspension and brake components. Same dimensions inside and out. Same option packages at the same price. The 1 ton is less than $1,000 more expensive. The ? ton typically has a 10,000 GVWR and the 1 ton SRW has a 11,500 GVWR. The 1 ton also has 1000#+ more Payload. That is a small price for much more capacity!
